That argument is not in the same category though. That doesn't even make sense.
Not same category, but same spirit. I act as the sole arbitrator to what miners are permitted to mine and earn. "Mine as long as you do not exceed x hash rate" is similar to "censor these as long as the network is sustainable".
You can not argue about miners revenue when the price has gotten dumped so much while hashrate has more than tripled in the same period!
I know that some miners' investment remains profitable, but there are tons of factors that influence the hash rate (let's please ignore them). You cannot just tell the miners they cannot mine x-type transactions, because
you believe they earn "enough" and because
you believe these transactions do not belong here (unless the hash rate needs them).
And then, you have a problem, because if your ratio of verification time to the new block time is too high, then you can reach the point, when you never verify new blocks, even if all of them will be downloaded on your disk.
Interesting thought. So, for instance, someone can attack BSV by simply filling the blocks with more than 600 MB data. I think their block size is 1 GB, so it is not a very expensive attack.
(I do not know if anyone still uses that, maybe it is already attacked several times)
