There is no such thing as a "Google Tax law" that is only applicable to Google. There are many laws and regulation trying to curb 'Multinational Tax Avoidance', some of which have been inspired by the elaborate schemes companies such a Google and others employ to avoid paying any contributions to the public that makes it possible for them to do business in the first place (Goolge 'Double Irish Dutch Sandwich' for an example). Your complaint of bureaucracy is valid. You should not be arbitrarily held back by irrelevant protocol. While Spain (and other southern European countries) seems to be very traditional in their adherence to formalism and procedure, nevertheless this seems to be advancing into a more agile direction. There is a difference between arguing for a level playing field, which I support, and arguing for abolishing all financial contribution to the public domain, which I oppose completely. As a last point you might want to look up why the taxi regulations were introduced in the first place, and how, while the 'mechanism' might be new (apps), the model has resurfaced every time there was an overproduction in the car industry coupled with an economic downturn.
