I don't see how that addresses what I said. He certainly doesn't rule out the notion of higher fees, does he?
Bottom line, that miner revenue needs to come from somewhere. I don't see the math supporting this idea that users can pay pennies (USD) for on-chain transactions forever.
I think He is stating the opposite: that rewards will be subsided by a high volume of transaction.
That's not the opposite. Satoshi's point that inflation subsidizes miners in the bootstrapping phase is pretty obvious. I can't elaborate any more on that.
You're ignoring the crux of what I'm saying. I'm not denying that he expected a high volume of transactions. There already are an extremely high volume of transactions compared to when he said that. What do you expect another exponential increase in volumes to do to fees?
Maybe in later BIPs we will be able to set sub-satoshi/byte fees..? Who knows. Only a fork is needed to do that.
In less than 13 years, the mining subsidy will be 0.78125 BTC. Could you give me an oversimplified back-of-the-envelope guess on where total block rewards and average mining costs might be at that time?
Why are you thinking in terms of USD value? 0.01 BTC was a perfectly normal mandatory fee in 2011.
