Just build more housing lol.

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.

That's similar to how it works in Singapore, where housing is fully public

The Soviets had an "apartment swap" system for people who wanted to move around filled-to-capacity neighborhoods. You would get on the list with where you currently lived and put in where you wanted to move and would get informed when there was a match. Sometimes matches would be arranged in triangles or other more complex shapes, but since everybody involved needed to get on the same page this was rare. The wait to move depended on how lucky you were - sometimes you'd get a match right away, sometimes you'd forget about it until ten years later when you would get a letter asking if you were still interested.

This was all in the 60s and 70s when things were generally more chill.

Humans could have this too if enough of us just started doing it

I think I'd be more like swapping different sized body armor, but I feel the sentiment;)

They kill/eat their dead, weak and handicapped as well. Heard they also get half off fries at Wendy's too no cap..Sounds pretty sweet op

socialist crabs.

I wonder how they communicate. There must be a signal that says, "I'm moving out. Line up!"

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.

If you found a house that was too expensive and tried camping outside it with your average wage in sharpie on a cardboard sign, nobody else would join in and reveal their earnings so nakedly. Nor would they reveal it in an online sorting list with their current house listed beside it..

Besides, you'd likely object to moving to their previous humble residence in Alberta where the older couple earned the retirement that affords them this house.

It's pretty sweet ngl.

In Australia we lose about six months wages to 'stamp duty' if we move. Better to stick with the oversized shell.

Iirc there can be a mad scramble. If two try for the same shell, one loses out and their previous shell may be taken. So they're fucked.
