I’m not certain why that’s an untruth, the use of cash has plummeted in the last 2 decades and will only make up 1.6 in 10 transactions by 2026: https://www.pymnts.com/cash/2018/uk-debit-cash/
You really think you should have to pay £0.60 for a £10 transaction? Bearing in mind all that’s facilitates is the transfer of the money from your account to there. Assuming 10,000 of those scale of purchases are made in a typical pub each year, that would equate to £6,000. For small public houses that is a lot of money.
I think the belief that you have to pay for all services is a myth. Intermediaries for intermediary sake, picking up a % of all transactions when they add little value is a problem. That it can now be addressed is a huge thing. I don’t understand why anyone would think it’s fair to pay for a bank. The whole fractional reserve model — you deposit X, they lend out 10X at 6% interest on loans, pay you 1% on X and keep almost all the rest meaning their reward is almost 50X yours is their payment. Business banking operates under slightly different circumstances, but the model is similar.
You’re talking about something entirely different, where there is a market being made and liquidity is required for transactions. For the services you require the currency is the same. £ to £. In crypto, if you exchange bitcoin from wallet to wallet the fee is a fraction of a penny.
Crypto is more precarious than gold in what way? Throughout history, gold has been incredibly volatile comparative to the FIAT currency of the day.
