You have very little evidence that this is true.
And anecdotal data suggests that explicit "social ranking" introduces a whole host of other problems. See: the kerfuffle about AirBnB and renting to minorities.
Congratulations. You just invented "zoning laws".
As well, maybe it takes a while before the true societal risks are understood, AitBNB regulations may be too weak for some reason, but until we discover that, perhaps we've "unfairly" put some marginal hotels out of business that would have survived under the impending new legislation. (Hope that makes sense?)
As I touched on a above, the thing about restricted markets is that price is able to rise artificially due to the unnaturally constrained supply. This ends up being a government subsidy; one that is disproportionally paid for by the poorest people. If you are already comfortable with subsidizing licensed businesses, why not continue to subsidize the marginal ones? Perhaps even in a way that is less impactful to the poorest people?
