Ah, it was mostly to your point that renting out rooms is fine as long as it’s supervised/closely looked at. Renting out to tourists is bad in my opinion, flat out. Tourists should be lodged at dedicated buildings (hotels/hostels) and the rest should be for local populace.
Evidence shows such “rules” are ripe for abuse though. Let’s keep tourists in hotels. That system worked for decades without outpricing locals.
