It doesn’t. Someone tried to apply digital key management to the physical world, and mapped it poorly. There is zero value in having each door to the same space have different keys. There is some marginal value in having different spaces having different keys (house, storage unit, detached garage), except that generally you will lose the entire key ring when you lose one, so the separation doesn’t net much.

I like different spaces having different keys. If someone is house sitting, then I can give them the one key they need and not worry about snooping.

Obviously a bad actor could get around it no problem, I’m just keeping out the honest

Different keys for what, though? Separate spaces? Sure. Front and back doors? Pointless complication.
