People aren’t in control of who sends their wallets coins and unless there is a notification system setup it seems like the tax responsibility would arise when they attempt to use the coin. Also if everyone were responsible for every trade that occurs within their wallets, and have say with one trade they make a large profit and owe the government taxes, then in the next trade they lose the profit, are they responsible for loss of government property? Also what about an auto trading bot that is run by a neural network that makes trading decisions based off key words in the news, if it is responsible for losing the would be taxes, who is to blame? It’s creator? The philosophical questions from this stuff pick apart out we normally think about this.
