Allow — Allows the other person to break your blocks freely without getting hit by anti-grief. When you leave the game it resets back to default (meta friends keep allow if set to allow)
Default — The current building mode permissions (people can pick up your blocks to an extent before anti-grief kicks in)

Edits to building:
Anti-grief doesn’t active if the player who placed the blocks isn’t in the lobby
Ability to transfer your blocks onto another player so they can own your build when you leave

I think this would make the ability to collaborate on building in wilds way easier than it is currently
