Unless you like munching on acorns, and living in a hut by yourself, then, bitcoin matters.
For example, you don’t even matter if you’re one of those weird vegan hippies who want to be detached from it all — in today’s world it is like physically impossible to live without money, without US dollars, without Apple Pay without your Visa credit card, your debit card or cash money.
People say that love of money is the root of all evil. Yet, this is misguided; maybe the whole time because the money was imperfect, the love of an imperfect thing was considered a vice.
But what if money were perfected, almost godlike?
Then, love of bitcoin would be virtuous! 
Money vs Capital
To me, the difference is I see money more like transactions, stuff you buy and stuff, whereas capital is actually the Apex desired thing; the true king & emperor.
Bitcoin is king
Why? It unifies all 8 billion of us on the planet, and we are not restricted by jurisdiction, laws, governments politics etc. Bitcoin is pierced; it is a political, righteous and virtuous. It is like gold perfected.
If you could store gold on the cloud, on your iPhone, your iCloud account, this is what bitcoin would be.
