Wife concerned BTC will be nerfed by ‘the system’

My wife and I have been discussing putting significant chunks of our savings into bitcoin moving forwards. She agrees the fundamentals are fantastic but is concerned about putting too much in in case the fed/traditional financial institutions do everything they can to try to kill it in the future to stop it becoming too valuable…

some examples - extremely high BTC specific taxes - manipulating the price e.g. by shorting BTC with unlimited quantities of fiat - criminalizing self custody - attacking infrastructure (exchanges, nodes, wallet providers) - undermine public trust in BTC to cause panic selling - offer huge tax incentives to exchange for some government backed coin

These felt like totally reasonable arguments to me - how do you all think about these possibilities? I’m leaning towards ‘possible but less likely than continuing to devalue the dollar’
