Answer: No it is not.
Explanation:
Uber by first establishing itself and then fighting regulators leaves itself open to attack around the world. This is because the Regulators have the power to keep adjusting the laws that govern Uber if they feel that Uber has an unfair advantage or if it's existence is detrimental to the society. Uber has been accused many times of various infractions such as Tax Evasions and being a conduit through which crime can be committed because it did not conduct proper background checks.
Going back to the issue of taxes, if the regulators feel that Uber may be avoiding taxes, they could impose laws that either cause an increase in Uber prices or remove them from a location which can have a native influence on Uber's bottomline.
This approach is not good because regulators do not like being fought and will try to ascert dominance. It is simply not viable and this has been proven with Uber's many suspensions around the world.
