I agree, but I think it is partially correct. I think one flaw in the theory is that the production increase is assumed to be linear, even though the labor pool is assumed to increase exponentially.
Another flaw is that population is assumed to be growing exponentially, while we already see that it is slowing down globally, and many countries even have declining population.
Anyway, the deflationary nature of Bitcoin was discussed many times, but my take is that it's irrelevant until Bitcoin becomes very widely adopted, which will likely never happen, so it will never have any macroeconomic effects. Also, this whole store of value vs currency argument is flawed, because people will use it however they likely. Bitcoin wasn't created to be one of them, regardless of what Satoshi said or wanted, Bitcoin is freedom, and freedom means Bitcoin is a currency, a store of value, and just whatever you want it to be.
