I currently don't own, and I can't either, because I don't want to be stuck in one place for too long. If the prices where lower, where I could reliably buy, live for some years then sell again, without a huge amount of hassle, and not costing at least one million to buy some shitty apartment, then that'd be preferably.

And besides just having "real estate investors" slurping up all housing, people could own one house then rent out parts of it, or a collection of people could own their apartment building together, there are many other ways to make housing work that doesn't involve huge companies owning large parts of the market. A little bit of nuance goes a long way.
