That is what BTC was designed for, you wont do your buying with bitcoin you wont be able to afford one, you will use fractions ie satoshi
If you read Satoshi's original white-paper, BTC was supposed to be for peer-to-peer payments. That is what it was originally designed for.
However, with the crazy value-increase and the escalating fees to transfer BTC, and the congestion in pending transactions, it has become more like "digital gold", in that people hold it as a store of value, rather than for transacting. So here I completely agree with you. I don't see myself buying a cup of coffee for 1000 sats any time in the near future
Fortunately there are a number of cryptos that are actually better for transacting than BTC, so it suits me to HODL my BTC.
