I wouldn't deny if me and most people in this forum still use fiat to pay daily expenses in our country, but I'm not holding fiat, I will just convert my Bitcoin to fiat whenever I need fiat. If the stores in my country are accept Bitcoin payment, I will directly pay with Bitcoin without need to convert to fiat.
Sure, I can agree that stablecoins have an element of shadiness to them. I definitely would not agree that established stablecoins are any more shadier than fiat money though.

I think that everyone should grow a pair against volatility and just use Bitcoin. Businesses need to accept it. People need to learn how to use it safely. If everyone had this change of heart overnight, fiat would be dead.
