If we say "no more profit after 5x" then buildings will constantly be torn down and rebuilt or otherwise "re-constructed" to reset the clock. Renting property has its own ongoing risks as any landlord will tell you, and we reward risk with (potential) profit.

Many buildings are "luxury" in that they cost 15% more to build but then ask for 50% higher rent. It's not hard to find buildings that were once "luxury" but are now kinda gross since the veneer has peeled off. But there's not enough competition in housing to force the rent lower.

What gets people fed up is the seemingly universal constant of rents raising 10% every year despite no additional investment.
