If by "many" GP meant "a small but noticeable percentage of the population", I think the claim is reasonable. Buying a home is a process. In additional to the standard search and short personal inspection you'd do for a rental, there's an official inspection, securing a loan, etc. It consumes a significant amount of time for a month. For someone moving every 6-12 months, spending a month or even two per year on buying properties and ensuring the previous owners aren't hiding issues isn't worth it. If a landlord hides something this type of tenant will only have to deal with it for a year at most, but if a seller hid something they would lose a lot of money on the move. Moving every 6-12 months isn't the default, but it's relatively common for college students and recent graduates who haven't established roots yet. Next year it's a new city for a different job or a different school. For example, for many fields in the US going to the same university for grad and undergrad is highly discouraged. (Not disagreeing with any of your other points.)
