Tangible drugs have inherent value: once you have the physical object, you can get high in the privacy of your own home with no further interaction with anyone.

Tangible drugs have inherent value: once you have the physical object, you can get high in the privacy of your own home with no further interaction with anyone. Cryptocurrency, fiat currencies, and arguably even metal coins derive their value from the existence of a market which will take them. Bring a bitcoin (as in a wallet private key, not the concept) to 1990 and nobody will pay you for it. Therefore, a government doesn't need to ban you owning cryptocurrency - it just needs to crack down on the businesses you would spend it at accepting your cryptocurrency. And it doesn't really even need to ban that, it just needs to crack down on their suppliers, and so forth. Your local pizza place that takes Bitcoin only accepts it because that money is in turn spendable by them to buy flour and oil and cheese - either directly, or by giving it to someone who will give them local currency with which they can buy flour and oil and cheese. If the government presses hard enough on those links, your local pizza place will stop taking Bitcoin, and then they won't have to ban you from owning Bitcoin at all, you won't be able to do anything with it.
