What Hacker News says
6 sourcesTo address your point more directly: many think that Bitcoin isn’t tangible because you have to trust that the network of full nodes are verifying transactions, and if they stop then Bitcoin ceases to exist.
Full nodes have financial incentives to run and they do so today at a scale that rivals the internet. It’s not a favor to Bitcoin, it’s a business. They would only stop if the financial incentive ceased to exist. I can’t think of a reason node operators would cease to care about their own financial well-being. That’s baked into our species.
Note that your reservations apply equally (and potentially more so) to fiat. USD is a virtual currency. Cash is on the way out. You will not be able to spend your USD offline. USD is based on a network of centralized banks. You cannot spend your fiat without a computer asking permission from these

centralized systems.
The world stops if the internet stops. That’s not a Bitcoin problem. Bitcoin actually improves on the state of things by replacing encumbant authorities and centralized computing systems with math and a decentralized network.
I’ll add this. It’s not the current state of the world, but there is a very real chance Bitcoin can be made available off-internet via a satellite network. This would prevent state-level censorship like what we see when authoritarian regimes cut the internet.

So this seems useless for payment, but here is the real hidden interest:
You can send a file up to 10Kb, and pay for byte sent.
It's cheap, coast looks to be $0.0035 for a 5Kb file.
The receiver can get the file, encrypted, without internet, using only a SDR tv card, amplifier and antenna, worldwide, in 10 minutes.
I see there large possible applications!!!
