There are tons of things that people do that I might deem not worth the environmental impact, like flying a hundred thousand miles a year for business, or eating beef, or driving to work every day, or having bigger houses and lawns than they need. Seems kind of arbitrary to allow most wasteful things that people do but draw a line at being able to participate in a certain kind of blockchain. The per-person impact of holding and transacting with bitcoin is not egregiously high compared to all the other things people do in their day to day life.
And based on ethereum's move here, perhaps people are starting to vote with their wallets anyway and such dramatic limiting measures aren't needed?
