This is probably not something a lot of people will agree with, but my two cents. The issue is autonomy and consent. If people are really owner of their own data they should be able to do whatever they want with it. They should be able to sell it. They should be able to exchange it for services. You can use WiFi for free. Why should that be frowned upon? It's your choice. We do not live in a nanny state. What should be clear is what kind of transaction you're in. What kind of data is collected. The deal should be transparent. You can't say that this data is valuable on one hand but forbid people to trade it on the other hand. Definitely not just with an argument based on autonomy.
