Bullshit. It serves the purpose of allowing more transactions to occur on the blockchain per unit time. Whether or not that is something you desire is irrelevant.
There is no significant and especially unique solution that provides or problem it solves. Its a tacit assumption that the introduction of a "better" medium of exchange solves something.
Bitcoin certainly provides unique utility as an appreciating asset. It has given me a place to park the fruit of my labor that has appreciated in purchasing power far and above any other option. And processing more transactions per unit time allows a larger proportion of humanity to take advantage of this fact. This itself is a "significant and especially unique solution that it provides".
