Capital gains tax is based on nominal price. You buy the S&P and it doubles in price you pay tax on that 100% gain when selling although the overall trade has only maintained your purchasing power.
If the Dollar hyperinflates except draconian tax measures to steal the nominal growth of assets. Hypothetically bitcoin could be priced at $1M (while $1M is really $100k of todays purchasing power) and the tax you’d be charged will be on the full ~million gain.
The devaluation of the dollar will be weaponized. Example: new rules where income over 10M is taxed at 90%. Then devalue to dollar so much any worthwhile asset results in effective confiscation when selling or trying to leave the country via exit tax
