Just wondering, does this make any sense at all?
Without reading the whole thing, it appears that his arguments all boil down to this:
It has to double in price every 4 years for a century or sustain extremely high fees!
Just to maintain the present level of security...
1. "
extremely high fees". The cost of the fees depend on the economic value of the transactions. Block space is limited, so only the most economically valuable transactions will be included. The fees paid for those transactions will be reasonable because transactions requiring unreasonable fees will not use Bitcoin. In simple terms, if you think the transaction fees are too high for what you want to do, then Bitcoin is not for you. None of this means that Bitcoin will fail. It will just fail for you.
2. "
maintain the present level of security". It is assumed that the present level of security is the
minimum necessary level of security. That may or may not be true. I have yet to see someone determine the minimum necessary security.
