Yesterday bitcoin's average transaction fee was over $31. Bitcoin Cash and Ethereum both exceed bitcoin's transaction count consistently now, with Ethereum far exceeding bitcoin's crippled transaction capacity.
It would also be interesting to see a large market event that causes many people to move bitcoin at once. (What happens to transaction costs? Does this affect perception of bitcoin as a safe store of value?)
Scaling only the price of transactions is NOT going to work, but it has quite a bit of runway to figure this out.
