Who pays for the infrastructure? I can drive 10 times faster with good roads because a public sector maintain and build road infrastructure. If that enables me to earn 100 times more am I then entitles to the entire profits? Or should I pay some of it forward to the infrastructure. I like the idea that innovation advantages should spill over to the rest of the society with the speed of inflation. Given an inflation of ~2% it should take me roughly 50 years to not gain any profits from my innovation (given no competition).
