I think everybody has to be obliged, at least once, to move within a year or two of buying a house, just so they can understand what it is to take a huge bath on closing costs.

And that's before you get to things like the furnace going, or the roof failing. Two kinds of people with this "landlords provide absolutely no services" perspective: people so comfortable financially that the y-o-y costs of maintaining a property don't even register, and renters who have never owned and been on the hook for an urgent big-ticket maintenance problem.
