So far you have described taxation and capital punishment. You must be a fan of Ben Franklin who said that death and taxes are unavoidable.
I suppose there is also the capital punishment debate. In the UK, the vast majority of people support the death penalty but parliament won't enact it. Having laws we disagree with is a pain.
The assassination comment was a tongue-in-cheek joke and had nothing to do with capital punishment. Answer the 50 pieces of gold problem.
Was there a problem? You described a rubbish way to collect tax. I can't see it working if applied to large groups of people.
