Subscription models and micropayments are not mutually exclusive, as in Spotify - you pay a subscription fee to listen to unlimited music. In practice that is the same as paying a fraction of a cent to the artist each time you listen to a song.

I would be willing to pay for a service that tracked each site I visited and billed me at the end of the month at a price-per-pageview comparable to CPM prices today.

EDIT: This is very distinct from asking me to pay 20 cents each time I want to open a particular page. The time I would spend considering whether to open a particular page or not isn't worth 20 cents, without regard to the fact that 20 cents/view is easily 100 times over the going rate for a page view.
