One model, in the UK at least, is to use an agent for purchasing of subscription publications.

This newsagent delivered the papers and magazines to your door before you left for work in the morning, didn't send your data to organisations and allowed flexible purchasing options (monthly, weekly, etc). Many people still use news agents for their subscription delivery mechanisms.

Perhaps we can see an online agent, where we pay a trusted third party that negotiates transactions on all our online activites on our behalf, and protects our privacy, location, when else we buy, etc. That digital agent would collect a small (1% of transaction cost) as fee, to continue it's operations.
