Going forward, all coins that are claiming to retain cash and gold's full set of features, need to deploy at least optional coin privacy on by default. Bitcoin is not, and is quite unlikely to ever be, that coin, and most certainly not under the current "dev" team.
While a respective level of privacy feature can exist. In the realm of old news gone without saying, all crypto, and modern digital fiat, is one good solar flare, impact, or EMP / war, away from zero and total chaos. At which point you have bigger problems. It will be equally difficult, without such event, to convince [1] the masses to ever go back to, or maintain any fraction in, gold, silver, tradegoods, paper fiat, etc. And in such event, the marauding masses who didn't will wipe out those who did. Everyone knows this. Civilization is just one big gamble anyway, unfortunately, for the time being, until off the rock. Live on. [1] The planet has spent at least 85+++ years going from gold to paper fiat, at least 45 years to digital fiat, at least 10 years to crypto, and 0 years to voluntaryism / agorism / etc. The masses first back to gold is thus a pipe dream. Better luck more likely from crypto to gold as a saleable backup plan to the new "crypto enlightened" masses.
