The complaint, real or imagined, is that young individuals aren’t building up capital. Home ownership was the bedrock of middle class assets.

Guaranteed those 100 individuals won't all raise their rent 10% (or whatever) on the same day, every n months.

I disagree with this logic. To take it to an extreme, if one person earning a million dollars per minute has moral value X, then a million people earning one dollar per minute has moral value X. I disagree on principle.

Just allow people and corporations to own any homes they build. That way we can all still hope to be landlords with a hundred homes.

So long as landlords grow their business by increasing the total stock of housing, no harm is done.

This comment always comes up when regulation is proposed: "But people will just game it!" The solution is not to throw our hands up and say "Well, we just can't regulate this!" The solution is to prevent the gaming, too. Laws should iterate as often as people find clever ways to work around their spirit.
