Try buying or selling a house with unlicensed "modifications". It's an interesting exercise.

Very true. Depending on the modifications (like electrical), insurance could deny claims if they find unapproved/unpermitted work, even if it wasn't the cause, or the cause was unknown (depends on the policy).

Around here, if you don’t want to buy a house with un-permitted work, it’s no problem; there’s another buyer standing right behind you (often literally) who will.

This is true but like i said when you need real permit etc this becomes tricky.
