If users are going to be put off by, say, 10-20 cents in fees, then perhaps they can buy plenty of lube and go get fucked by the banks and the paypals instead. Having 1-2-3 cents in fees and complaining that it's the end of the world if we go upwards and that it's crippling adoption, when RL banking payments are charging the hell out of us (and they are being used everyday by billions of people) and we get fucked by them constantly, is somewhat hypocritic.
Besides the main selling point of BTC shouldn't be an addiction to near-zero cost txs (which we know that is not sustainable in the long run), but rather its decentralized nature and its advantages over central banks (as a token/currency) and commercial banks in terms of controlling your money, paying without trusted 3rd parties which could withhold or confiscate your money, the non reversibility of (confirmed) txs etc etc.
It's not 20 cents in fees. It's $8 and it's being subsidized by you and me, the buyers of BTC.
And it's not decentralized with 75% of the mining in China. We are operating with the required permission of The People's Democratic Republic of China.
Actually, there seems to be a decent point, that mining costs are not just for the present block being mined.. but for the future and for the speculation.
Wow...
In other words, the calculations are not so simple because the amount paid by each miner to mine is not a cost born on users as individuals or even in the aggregate.
Yes, some of those speculations will win, and some will not.. and over time, some miners will stay in the space and some will exit.
