good answer. thank you for taking me on. does it justify theft though?
Many people support large amounts of free market activity and decentralized economic agency, but most people believe that only relying on this model of human organization will bring significant harm to society.
Very few people consider the idea of "taxation is theft" to be even remotely reasonable.
Thus there is a fairly large gap for you to bridge when trying to make points that rely on such principles.
I think the LHC has over a dozen participating countries, each of which volunteered to be part of it. Ideally there should be checks and balances making sure a project of this scale is free from corruption.
That costs money. It requires the work and agreement of others. You are not entitled to that for free and without entering into any sort of negotiation that involves give and take.
Your demand for protection against that thing you call "theft" is essentially a demand for the existence of a system of government, and that requires taxes. Therefore the claim that taxes are theft contradicts itself.
