Software, books, musical scores, etc may indeed have tremendous value
But Bitcoin is a digital collectible, not a set of useful instructions. The ledger technology is a set of useful instructions, but owning Bitcoin is not necessary to execute the (open source) code to run a distributed ledger.
Let me put it this way: how much would you pay to be the only person on Earth who was entitled to receive Bitcoins? You get Warren Buffets' hypothetical offer to buy all the Bitcoins in the world but you also can't sell or trade them. Zero, yes? All they're good for is trading
In contrast I'd pay at least slightly above zero for a lifetime supply of beef, seed oils (which make good machine lubricant even if not food) fiat paper which I can take notes on or burn for warmth
So why should the recipients of your bitcoins be willing to give you a service or some useful commodity in exchange for them? Only because they can trade them to still further recipients
