The issue I have with analytics, additional to your (imho) valid points is that lots of practical users seem to always measure the wrong endpoints and don't include negative outcomes.
Leads are useless without measuring how many people bounced off your shitty online shop, because they couldn't understand your UI.
Staying time is useless without measuring closed tabs, because your website is unreadable with ads.
The irony behind it is that ad metrics are used to buy/sell a website's worth for ads. Sometimes I feel like it's like a bubble that's invented on purpose to not have a measurable outcome of anything.
I agree with you in theory but I'll point out you do measure bounce rate and reoccuring vs new visitors and staying time at the same time to give you that exact view.
But I agree they measure the wrong end points or rather they measure too many end points for me to make sense of which one is better. The goal of overall traffic sometimes works against keeping bounce rates low or staying time high.
In the end you would think products sold matters. But an over promising website will over hype and under deliver causing returns or bad reviews which may affect future sales. The message has to describe the product but still meet the market's demand.
