That's definitely true, but that still leaves a pretty large potential market for home owners with garages (i.e. people for whom an EV is a decent value proposition) that is far from saturated. My guess is that by the time the garage owner market for EVs is getting tapped out, the charging problem for everyone else will have been solved as well.
I also think the market forces work the other way around. I currently own my home, but it's a condo with a shared parking lot and no way to charge an EV. I've been looking to upgrade at some point, and one of my non-negotiable requirements is that whatever I buy next needs to have a way to charge an EV at home (private garage with power, shared parking with the ability to install charges, etc). As EV market share increased, I expect this to create more and more pressure on the housing market to meet home charging needs.
