We can't have the same right now because these companies are so focused on making targeted ads work. Which is not because it works so well but because it's their #1 market benefit. Facebook wants to sell targeted ads because few players have as wide reaching insight as they have.
Once they have to stop they will have to actually put effort in making contextual advertising work. Imagine a local business sponsoring a related Facebook page. Or buying ads for declared interests.
It can work but the big parties don't want it to. Because they've invested billions in building their market advantage in targeted.
Also you are assuming you can have 'same' service after banning targeting. That remains to be seen.
Also, you could consider disagreeing without being rude.
