I actively prefer ads for things I might actually be interested in purchasing. If there were an option to tell advertisers "Please show me more ads about..." I would take that option. whenever I was waffling on some purchase. Most ads suck even so - they don't actually tell me about a new feature or fact that could potentially change or spark a buying decision - but at least it's not a total waste of time.

The only economically productive use-case of marketing is to lead trades to take place that would not have taken place otherwise, or higher-quality trades to take place; which can have its roots in consumer gullibility, but ideally reflects some new company telling me about a relevant product that I didn't know existed. This happens rarely. Having it happen more often sounds like a good idea to me.
