Nah I agree with you. Not this century, not this planet. Fusion rockets are really efficient, though ;)
I just find it to be an interesting problem! My hope is it happens before I die. My rule of thumb is anyone who says energy on the grid in < 10 years is a blatant liar.
Oh, I think energy on the grid in < 10 years is probably technically feasible.
It's just probably not economically feasible, ie it would be a waste of resources to rush fusion so much.

Ha, that's why I was working Zero Knowledge Proofs for quite a while. I don't even hold any cryptocurrency or other crypto assets.
I agree that you can build a facility to put energy on the grid in under a decade, but the probability that it works is going to be tiny, and anyone giving you the billion or so it would take would be disappointed to say the least.
Therefore, most credible folks are talking a 2-3 facility staged approach. And probably 5 years per facility to build, and 5 years per to test.
Also, remember that even with huge cash pools, you have supply chain problems. Some of the nonlinear optics takes a fixed amount of time to fabricate.

A giant water tank that you detonate H-bombs in should work, and even be energy positive. :)
