In practice, it does. It's impossible to use any of the major ad networks effectively without conversion tracking (which is what I'm assuming you're calling selling out? I disagree with that sentiment, given it amounts to sending a single pseudoanonymous ID with user consent).
Edit: To be clear, most European enterprise companies would happily dump Google Analytics if not for Google Ads and the Search Console integration. Almost all will be already be using another tool for user analytics, but most online B2C companies are reliant on Google for demand generation, and Google Ads is only effective with conversion tracking.
Does conversion tracking require you to track your users (a la google analytics), or is it actually just a pseudo'anonymous' parameter when visiting a website (like referrer could be, if advertisers hadn't killed it).
And even then, advertising without tracking worked just fine without internet.
It requires getting consent and sending the value of a query parameter that was appended to the ad link the user clicked (GCLID for Google, FBCLID for Meta, etc) with some random (but now pseudonymous, because Google/Facebook/etc can link the session ID to the click ID to a user account) session ID and then sending that same session ID when the user converts/does the thing you want.
If you get consent, you can also set a longer-lived cookie to determine if a user converts in a future visit.

There is even now a form of online advertising without any tracking (except in the most opt-in form of a discount code) which is sponsorships of videos, podcasts, articles, etc.
However, for search and display ads, which drives a huge amount of traffic to EU businesses, there's no effective way to run ads without conversion tracking. Obviously you can just throw money at Google/Facebook, but without conversion tracking, the average return on advertising spend will be 1-10% of what it would be otherwise and you will pay for a lot of junk traffic.
It's not unusual for B2C companies in the EU to make 80%+ of their online revenue from forms of ads that require conversion tracking, so it's impossible to expect businesses to refrain from online advertising unless all their competitors are required to also.
This all relies on getting consent as a lawful basis for processing, and is currently acceptable under the GDPR except that the major networks are all US companies who could be compelled to transfer the data to US authorities.
Even now, it is much more likely that a US CLOUD carve-out or other work-around for an adequacy decision with the US will be made than the CNIL interpretation will be followed to its logical conclusion, which is that EU businesses process personal data with any US-controlled vendor, even if it occurs in the EU.
Sorry for asking so many questions, but I don't know much about this and you seem knowledgeable.

1. Can you not track conversion in aggregate by running X number of ads and checking how much extra traffic you got? It's obviously noisy and you can't run multiple campaigns at the same time, but conceptually I don't see why it wouldn't work?
2. I'm assuming you put links in your ads, so if you run ads for lander.example.com, can you not put the URL in google/facebook as lander.example.com?src=g and src=fb? Or, if you can't use query params, g.lander.example.com and fb.lander.example.com? Tracking stats for those and seeing how much ads you ran should give you conversion, similar to 1. but better?

You can and many companies will have a first-party (or partly first-party, feeding into PowerBI or Tableau or something) system for this kind of reporting completely independent of the ad networks (to independently verify the numbers the ad networks claim, to include other data that a company would never share with Google, and for fraud detection).
However, without conversion tracking, Google Ads' "Smart Bidding" and "Remarketing" targeting features don't work. For a lot of businesses, being unable to, for example, stop advertising to existing customers or to use a certain bidding strategy means that the Return On Advertising Spend (ROAS - the big metric for enterprise marketing departments) goes below 1.

Companies often do this, with Google Analytics-compatible UTM parameters, custom source IDs, and very often unique marketing landing pages for each ad campaign.
As above, though, reliable reporting of conversions/revenue isn't the difficult part. It's being able to reliably target the ads/campaigns without conversion tracking.
Right now, targeted search and display advertising can be 10-100x more effective (in terms of Return On Advertising Spend) than keyword- or context-only targeting. That's not an advantage a company can forgo unless the entire market is forced to simultaneously.
Wat.
You can't sell out your users to google ads, that doesn't mean you can't advertise on google.
