What do you propose we replace it with? Or rather.. when people who have money want to buy market share, what do we tell them? As long as capitalism is a thing i think we are going to have advertising. Big industries like advertising don't just go away.
Ideally: fuck off, put that money into wages and high quality products, getarkrt share organically.
Intermittently: all advertising only gets put on platforms that explicitly aggregates advertising (maybe even need to get a license), banned everywhere else. Users who want to get advertised to can log into this website and browse ads. Your money buys you exposure on these sites. Kind of like we use producthunt to find new good shit.
Advertising us stochastic coercion: whether I pay you 1mil to force 10000 people to buy my shit with physical force or to use psychological tricks to nudge 100 million people and it works on 10000 makes no difference morally
