Besides all the possible threats on anonymity which are there if you have
to pay for something, (how do you actually pay for something
without coming close to money laundering?): which entity shall collect the
money and re-distribute it to the operators? How do you deal with international
money transfers? And (as somebody else already pointed out): how do
you assure that everything remains fair, i.e. that paid traffic is prioritized.
All these academic publications make is building castles on sand - the most
difficult part is actually to have a working system for international payments
which has a small enough overhead that it can be used for these kind of transactions
AND is privacy friendly AND is accepted.

I guess not. There is already a Tor network clone which is for paying customers
Maybe, making Tor a paid solution would even help because the money could
be used to handle the overhead which is
created for the operators due to all the
idiots abusing the network. Maybe it would even keep the idiots off the network :)
But then: IMHO it is not possible to make it work anyway...
