Regulation is when individual action isn’t enough.

Regulation is a form of collective action.

And it doesn't even need to be government regulation.

The hospitality industry has self-imposed standards as to what kind of amenities a facility should have in order to rate as a two-star hotel, three-star hotel, etc. Things like TV, shampoo, and hair dryer are on that list. If customers make enough noise about bathroom doors, the rating organizations might actually add that as a requirement.

Regulation isn’t a collective action, at least not in the US. People don’t regulate hotels will ballot measures so you’re left with whatever the whims are of some representative.
