> eg: owning a domain name

I just want to comment on the only tangible use case you mention.

What happens the day a rogue actor gets ahold of .gov, NSA/CIA/DHS, or Google's/Microsoft's domain and sends it to /dev/null?

The "no central authority" point of Blockchains is too risky.

Ps, saying that Blockchains solve the double spend problem is like saying the iPhone solves the "running-out-of-battery" problem; it comes with a charger. Nowhere else do we have the double spend problem, simply because we have a CA.
