This was accurate as the block reward via inflation is what subsidizes the transaction cost down to 2 pennies. The cost has been steadily dropping and will continue to do so.
I.E...
If there was 130k tx in a day and ~3600 btc mined in a day this would indicate an extra 997k in inflation/ 130k = 7.6 extra per tx + 2 pennies mining fee or each transaction costs 7.62 and most of that is being subsidized by inflation.
Bitcoin can scale without centralization but we will need sidechains and interpayment channels like the lightning network to allow it to and lower the cost of transactions.
