Lets have slavery as an example. You feel uncomfortable abolishing government completely. That's fine. How'd it work with slavery? Imagine we decide that slavery is not good. Should we just let every slave run away (at the expense of cotton plantation owners who'd immediately incur losses)? Or should we release every 10th slave this month, then every 9th next month etc.? Is it then moral to shoot down a slave who'll be freed two months from now, if he runs away today?
