If there are any other arguments - real arguments - pay attention to them, but the equity concerns should be filtered out of the conversation and their advocates seen as having wasted people's time.
The idea that ideas can be owned is the defect. It's an idea you had. It's not your idea.

If hypothetically targeted ads would be banned, there would be the same advertising budget as before
Not really. The 2x $1000 or so I spent on targeted ad campaigns have been worth it. If they weren't targeted, it would be far less effective; there's quite a few articles pointing out that targeted ads have a far higher click-through rate, and a higher conversion rate as well. Without targeting, my ad budget might still be $2000 but I wouldn't be spending it.
The trouble with money is it costs too much!
