So far at least, all of Google's for-pay services are relatively niche/targeted at power users. I use Google products EXTREMELY heavily and I've never had occasion to consider a paid service of theirs. I think the overlap between "fix the interwebz" people and potential customers for paid services would be approximately zero.

It is possible however that what you're saying will open the door to charging for less niche services, but that's a whole 'nother can of worms.
