While your larger point is valid, it's missing some important context. I haven't seen the data, but I suspect that it says 65% own (vs renting) their primary residence, not that 65% own a single family house suitable for home charging. This figure would include houses with street parking only, off-street parking unsuitable for charging (e.g. carport, or a detached garage without electricity), and critically, condos. Condos often have the exact same restrictions as apartments, even if you own the living space. In the opposite direction, it doesn't count the rented homes where you could charge.

Now, all of that being said, you are correct that it's not the only (or perhaps even the biggest) obstacle to moving entirely to EVs. Countless gas vehicles are sold daily to people that could absolutely charge at home. But it does freeze out a large market segment, whom I suspect are more interested in EVs in the first place.
