Mnah, who would use your blockchain? You still do not understand why BTC is valuable - due to its usecase, many users, safety, decentralized. But you don´t offer anytihing new.
Nobody is doubting the value and importance of Bitcoin. The new thing introduced in this mining token is the way you can mine. You don't need traditional expensive mining devices along with huge power. MASS can be mined on computing devices using their storage space, though complexity is increasing day by day.
What you're describing above as a response to @Pecunia is that to start with the mining is relatively inexpensive because most of it it will be done on computing devices' storage but isn't this just the early stages of MASS?
If you really see potential in this new coin then you'll come to realize just like in the history of BTC mining that this computing power will get more and more demanding with time. SO based on what you're saying this possible issue isn't even on the table...by that logic the conclusion is that there's no need for MASS when it essential doesn't do anything else better than the already existing blockchain
