This would force these places to:
 a) use bridging to get that single /64 onto their network
    thus making firewalling really difficult.
 b) get a 'power users' abo, which would thus make people have
    to PAY for getting more IP addresses.

ISP's are paying their transits by paying for the *BANDWIDTH* usage.
So why don't ISP's have a couple of classes (to keep it simple) which
are like eg:
  10Gb account
  50Gb account
 100Gb account

This would also solve the "Those stupid users are torrenting" problem,
as they are PAYING for the traffic and other costs that you actually have.

Don't charge for IP addresses, charge for *BANDWIDTH* usage. If I have
200 devices on the network which don't do a thing (maybe they are light
bulbs or it is my fridge) I will do much less traffic than one single
user who is trying to complete his nature movie collection.

Scratching the 'power users' concept, as they belong in the above home
user part, I agree.
