I think it's not possible for now, because people can still use e-money which doesn't need to be touched by hands and the value is controlled by the government so it's more stable than bitcoin and other cryptocurrencies.
The idea behind bitcoin is that the government will have less control over the currency and i am sure in this day and age when government can come up with stupid policies that could ruin the countries economy and there are many instances we have seen the blunders in financial policies ruining the entire financial system and with bitcoin people can save their hard earned savings in a decentralized currency so that their valuation are kept intact and you should take these into consideration as well.
