Again though, you shouldn't be expecting practical results already. The short term hype soaking up vast sums of money is just an overreaction to a technology that will still take many years to develop proficient programmer/user experiences and public trust before it sees real use. Being skeptical of every current project claiming they'll be the ones left standing a decade from now is only smart - it's a giant hype market built on dreams. But you shouldn't be so doubtful that a relatively-uncontrollable internet consensus layer won't be built upon with some interesting results down the line. And that has clearly been created, and proven with decent security already.

I absolutely should be expecting practical results, because most of the people trying to apply this technology are promising practical results. If blockchain proponents were just saying, "Hey, we're fucking around with some tech to see what happens," I wouldn't have any complaints. But that's not where we are. Instead, it's billions of dollars of investment.

Is it possible that there will be "a relatively-uncontrollable internet consensus layer won't be built upon with some interesting results down the line"? Sure. Lots of things are possible. But it's also very possible that after another decade of Bitcoin, et al, we'll still have just a bunch of stuff that's not adding at all to the world beyond a playground for scammers and some tooling for light financial crime.

Sometimes a small and ugly technology turns out to be the Internet. But most of the time, it's just a bit of garbage that never went anywhere.
