If ads just vanished, that would be great, but making it illegal ought to do more harm than good. For one, a lot of ad money would be routed to shills, which are far more pernicious and have already infested otherwise great platforms like Reddit. Everything would turn to crap and no adblocker would help you. An ad ban would make every influencer profile instantly worthless, unless they decide to shill, which they're probably already doing anyway.
Also big tech would be incentivized to sell even more user data, as their business would still mostly exist, either via subscriptions, or through the now even more profitable user data market with more expensive targeted shilling.
