For an org that has an enduring billing relationship with the customer (think the large tech companies and platform providers), they already are handling transaction aggregation internally to an extent - just not to the extent of micro-transactions (where they need to handle the edge case of a tiny single transaction in a day or week or month). If you make a few app store transactions in a day, I believe apple aggregates these into a single transaction that's posted to the card. That model could help here, though obviously it won't help for ultra low usage though. Pre-paid models might work, but those have their own challenges, and all of this points towards a centralised gatekeeper knowing everything a user reads (or at least which top level publishers they read content from).
