Annoying things such as paying taxes, recycling/not polluting etc.?

Some things really can only be solved via central coordination, as there is no natural game-theoretic/purely economic path from one local minimum to another. Being able to dig a small trench and letting gravity and water do the rest is great, but sometimes you do need a pump.

I'm not convinced that IPv6 is such a case, but if it is, that's exactly the type of thing governments are much better at than markets.
