Don't forget that if you see ads online or during shows and movies it's because you are choosing to consume content. The ads are how that content is funded. It's the content makers and/or content venues that buy the ads, not the advertisers. The ads are there because you and I aren't paying for the content we consume. We could get rid of a lot of advertising if we paid for the content we consume, but we choose not to. This ad-driven model allows content producers to get their material in front of many many more people than they would have otherwise since they get to offer it for free.

BTW, ads are taxed, I believe the OP's point was that ads should be taxed in the locale in which they're shown, to give back locally rather than concentrating the tax revenue wherever adCorp is incorporated.

I used to be as against ads as you are, and then I tried to start a business. In today's landscape, it is impossible to get people to try your product. There is so much noise and clamor for consumer attention, and there are so many amazing choices for free content, that if companies aren't sending out reminders that they exist, most people will forget.

Overall, I'm in mild agreement that society would be better if it weren't ad-driven, but that's a utopian ideal we can't change with taxation, that's a brand new society and a brand new government. Taxing ads more won't make them go away, at all, it will just raise a few tax dollars. I'm in favor of using taxes on ads to pay for psychology and statistics education for all.
