Frictionless billing is harder than it sounds, because it opens the door to frictionless fraud. If I can automatically bill you for a thousanth of a dollar I can automatically do that hundreds of thousands of times. If it's with bitcoin I can obfuscate the destination of the money.

Agreed. Question is whether it's harder or easier than restricting traffic fraud, and if you can comply with know your customer laws and still protect privacy.
