Your controversial opinion is not bad as a vision. But I don't think it would work out that way unless aforementioned significant societal changes occur.

As a newcomer, you won't be able to buy a home. Similar to now, there will be many other more wealthy people who want to buy that home "as an investment" so they can keep growing their wealth in relation to their peers.

I already fear we are heading towards economic feudalism. Throw in living forever and I fear something more akin to SLA Industries: https://en.wikipedia.org/wiki/SLA_Industries

As you say though, with people pushing for things, hopefully significant societal change would avoid such a disastrous future.

edit - more concise.
