The perverse incentives exist right now, and "not even nefarious, but just spent on swaying the opinion of others to my benefit" actions are committed all the time by present day corporations. For example, there was a time when Microsoft tried to snuff out the open source movement. What did the goverment do? Nothing of course.
Maybe I just literally give some people units of currency to vote a certain way.
This actually happened with some DAOs. Many people here hate Ethereum but I don't. IMO experimentation that Ethereum does is very valuable, even if it's mostly in informing us what not to do.
The resistance of the anarchist society to vote bribing should and will be built and battle tested in a purely digital environment first, where the government can't prevent us from experimenting. The credibility of anarchy working in meatspace must be demonstrated in cyberspace first. (How are Ethereans doing on the DAO front? Not that well so far IMO but there's hope)
