I don’t really see a problem with it either. I pay more in some other countries too as a tourist. Here it’s framed as making tourists pay more, but it could also be framed as keeping the museum accessible for your population which does not necessarily have the same budget for museums as an international tourist on the trip of their life.
But: Tourists absolutely do pay taxes. There are accommodation taxes on hotel stays (in France this can be up to ~15 Euro per person per night), they pay consumption taxes like VAT, and there are arrival and departure taxes or airport taxes.
