Ah, I was looking at it from a system level. Make it a highly lopsided financial cost for a company to use data that hasn't been consented to, and the huge number of people keeping tabs on them would make it financially ruinous for a company to try and skirt the rules.
End outcome is the same - peoples privacy already has a price. That price is just currently only represented by FAANG profits.
In the US the civil courts dole out rulings requiring the injured party be paid by the offender when enough evidence has been presented. It’s not perfect-money can’t right all wrongs and the valuations can be problematic-but it can act as a counterbalance. Making it a law would mean a company would risk losing their ability to continue as a business following a successful conviction. In the US this has been turned into rarely indicting companies as the government doesn’t want to destroy whole companies that way and give other companies undue market power, or something.
