That sounds a bit short-sighted TBH. I am all for protecting "licensed" taxis from Uber et al, but the (long-shot) goal of robotaxis is providing a level of service that can't be provided with human drivers because it would be too expensive. If using robotaxis becomes cheaper than owning a car, that would get rid of most of the cars parked 95% of the time that are clogging up streets all over the world.
