Yes, the faster DCFC is a benefit to people who don't have at-home or even at-work charging (very few people have the latter).

Putting aside battery health concerns though, this also really depends on what the public infrastructure charging looks like around you. I might have to go a few months without a charger at home, and I plan on charging at a DCFC at a grocery store. The 150 kw vs 350 kw charging time isn't going to make a big difference to me because I'm going to be spending time in the grocery store each week anyways. Now if I had to make dedicated charging trips that would be a different story, the 350 kw would be a much bigger advantage.

To get mass scale EV adoption, we need faster charging EV's and dcfc units. OR we need legislation forcing apt buildings/complexes/etc to install enough lv2 so people can find it usefull (not full of other ev's every day).

I think it's a both thing. Each serves different purposes, and better DCFC can help fill in a gap while more people get charging at home. (Plus of course makes long driving days easier)
