”We have purchased something (stock, commodity, collectible, ect) that we already own and has gone up in value and if we decide to sell it, the government has a right to take a cut. Why? Because the trade is happening on their land? It is absolutely ridiculous.”

Lest also not forget, the history of “their land…” THEY being FOREIGNERS who came from overseas and MURDERED the local population, raped the native culture, outright fucking everyone in the way. “They” have no natural inherent right - it was thrust upon the people coercively, violently, in violation of human rights.
