Isn't the problem with banning ads that you'd just gets "ads" that aren't marked as such? Like, ads are still going to happen, they just won't be clearly marked cause that would be illegal.
EDIT: Would love to hear how the downvoters would enforce an advertisement ban. What happens when an influencer randomly endorses a brand and then that brand also just coincidentally happens to give the influencer a "generous donation" or perhaps a life-time usage coupon?
