> That was true when bitcoin was 2 cents
I largely agree with you, but to nitpick: when bitcoin was 2 cents, blockspace was free, and miners regularly accepted zero-fee transactions into blocks. Today, you're not getting a transaction into a block without paying at least a couple hundred sats. Your statement is true today, but it wasn't like this until April-May 2012 when Satoshi Dice started filling blocks up. See Fig 3 on page 9 of <https://maltemoeser.de/paper/transaction-fees.pdf> or look through some early blocks.
