It will be easy for single families to outbid a multi-million dollar corporation for these homes? What sort of buying power do you expect these families to have, relative to this enterprise?
The enterprise has more buying power but will also want to turn their investment into a profit. So whatever they do with that land ultimately needs to pay off. For it to pay off it needs to create enough extra value by being in that location.
Could it also be the case that investments driven by speculation and market manipulation would obscure the actual ROI (a lá Uber)?
Long-term the intuition is "this must be profitable at some point", so the market participants are acting irrational in the short-term. No one can compete with irrational actors, especially ones with an insane amount of capital to burn like we see today.
If you think the market is irrational, bet against it. Just claiming to know better but not putting your money where your mouth is and not having skin in the game is a anti pattern that's advisable in this case.
