Got to witness crabs doing this when going for a walk one day. There was a very shallow pool on the beach, about a foot wide, and about 20 crabs having a ‘swap meet’, scurrying back and fourth between the different shells.
Humans could have this too if enough of us just started doing it
Seems more analogous to clothes than housing — clothes can be “too big” in the sense that the extra size is detrimental to the function, which is somewhat different from houses.
And it’s pretty common to have buy-nothing groups in cities or even at large companies. Got a loooot of hand-me-down clothes for my toddler from friends, family, and randos in the neighborhood.
Yes and no. I’m sure there is an argument to be made that a house can be too big. Bigger houses require more maintenance, cleaning, higher taxes. Downsizing a house is also a retirement strategy.

Seriously though, if crabs used currency this would never happen. There would be one crab with all the shells and the other crabs would have to bring food offerings or whatever their currency would be in order to get one.
