I am actually quite sympathetic to libertarian thought but I never hear any concrete suggestions for dealing with complex issues like nuclear power safety, pollution (especially toxins where the effect is not that clear), public health, food safety and others.

For example: Innovation in self-driving cars would be much quicker if there was no regulation but how do you balance that against people not wanting to get run over by a car with buggy software? This would be an interesting discussion. Twitter is just a too easy example.
