I can't what? Pick a side or have money in both worlds.

I don't see how fiat looks bad? Fiat world reserve currencies are very useful. Being the issuer of such a currency is a huge advantage for an economy.

I have at times hand money in both worlds but because of crypto's volatility and the potential for government actions to restrict crypto, I am not comfortable hodl of any large amounts of crypto.

The dollar's value changes very little day to day and rarely changes more that a few percent a year. Crypto's value can change a few percent in a day. I spend thousands of dollars each month, price stability is important. If things were priced in Crypto I would need to check valuations to pick the right time to make purchases.

There is a story about someone who used Bitcoin to buy a pizza. That pizza cost what would be today a fortune. If the value of Bitcoin was to continue to rise (which seems likely) that deflation is a huge disincentive to making purchases.
