Block chain as a concept with the single use case of store of value has been around since 2009 in the form of Bitcoin. So let me only pick one battle here: The problem is federally-issued inflationary currency. Bitcoin solves it.
So far it is only proving that it cannot be both.
For assets, one can choose to invest in already existing inflation resistant assets, and many investors and even unsophisticated laypeople did that across the ages before Bitcoin was invented. So essentially federally-issued inflationary currency is not really a problem of investment because there are other alternatives to it when investment is concerned.
As an asset class BTC solves yet another problem: It is a better version of gold due to the hard supply cap.
Gold is the least good example among these kind of assets, because ownership is less bound and provable by law. Stocks and real estate are much better in that regard.

Or is that why Bitcoin is "worth less", too?

My point was: BTC is more deflationary than USD. A relationship between the topic of the study and my statement does not exist. But if you read chart 1 of Figure 1 carefully, you will find that its data in fact supports my statement.
