There could be a moral issue made, as opposed to a slave based fear, about standing up against institutionalized fraud..... but that aside, as you said,

Capital Gains are only due when you actual make the profit,,,, HOPEFULLY most people do NOT have their food and next months rent money invested in cryptocurrencies,,, therefor no one should be changing their cryptos to fiats.... Just hang on to your cryptos till you can buy stuff in cryptos and problem solved,,, 100 bitcoins = 100 bitcoins,,, no capital gains.
