Do you get paid in something physical? Do you think there are notes or precious metals sitting in a safe somewhere that you just never use? I suggest you study money. Also don't use the word whom unless you know how to.
I could keep going. There is a reason that even in countries like Australia where we have widspread tap to pay that cash is still pervasive.
"the lack of connection to something physical" - one can also argue about this. Money in your bank account is pretty much virtual too. If everybody right now wanted to withdraw their money from their bank account into physical money, we wouldn't be able to do that. There just aren't enough paper notes. Far from it in fact, it wouldn't even be remotely possible.
The biggest hinderance to bitcoin becoming a global currency in my opinion is the fact that governments are very scared of having a currency which they cannot control. Printing money is a wonderful thing to have for governments.
And for a good reason. See: https://en.wikipedia.org/wiki/Great_Bullion_Famine as one of the examples.
Bitcoin becoming a global currency would set us about 500 years back when precious metals were the global currency.
Not sure what point you are trying to bring across.
Also, no one is forcing you to use Bitcoin, Your government, however, forces you to use the state-controlled money.
Also it's really just a terrible idea. The volatility, the fraud and ease of theft, the lack of connection to something physical, the fact it undermines banks whom serve an important purpose. No thanks.
