I don't. I don't think it's literally zero - even if it drops to $.01 some people will still buy it on the theory that it might go up to $.02. But all of its value is speculative, I don't think it has any intrinsic value (which is equivalent to saying I don't think participating in the crypto economy, smart contracts and all that, has value). And the reasons are as explained in the article - beyond avoiding regulators, it doesn't allow us to do much that we couldn't do before, and what it allows us to do isn't all that valuable.
Even if I knew with absolute certainty that I would never be able to sell it for a profit, I might still buy gold, e.g. to make conductive wire. That's the intrinsic value. What's the equivalent for BTC? How many bitcoins would you buy if you knew that you would not be able to sell them for a profit?
