Whales will do what makes the most economics sense, i.e. that which is most profitable. Thus they will do what I wrote.
Math and economics game theory isn't something you can argue with. It is either stated correctly, or you must point out the error. There was no valid error pointed out by anyone about my logic.
I wrote "I think" as a way of saying I am open to reading anyone valid errors in my logic. So far, I have seen no such valid errors pointed out.
The future has not yet come to prove (or disprove) anyone's logic.
To say one's logic of the future is correct as of today, is to suggest self-fulfilling prophecy.
Spiritually, that is akin to handing one's creative power to a 3rd-party that does not have one's interest at heart.
The only way I can see that the fees won't rise egregiously on BTC on chain (with $trillionaire/$billionaire whales free riding on the rest of us) is if something can compete with Bitcoin such that the whales feel they are losing control of the blockchain (and eventually global) economy, and/or if fungible money can be removed as important from civilization.
Neither of those two caveats are likely to come true in the near-term. TPTB already have their master plan underway for collapsing the global economy in sovereign debt collapse with $quadrillions of derivatives, war, and pestilence. This will accelerate this May 2017 and even more egregiously accelerate in 2018.
Such caveats might start to become competitive with the plans of the global elite after another decade or so. In the meantime, such caveats will be nascent fledging saplings that are growing very fast, but not yet large enough to compete with TPTB.
