1. The same research that brought us the atomic bomb brought us so much more. Who cares about the motivation of the research? This is such a bad take considering the history of technology evolving out of military development.
2. Again, all technology is expensive in the beginning. Who cares? The important thing here is to climb magnitude by magnitude. NIF climbed many magnitudes in recent history, making it notable.
3. As you mentioned, Helion and direct energy capture. D+He3 + DEC might be not feasible with a tokamak, but the scaling laws of fusion (size, current, B field) are in favor of experiments that get close.

I think you have a very negative take on what is an amazing breakthrough accomplishment. Even if the NIF doesn't end up converting their research into a commercial powerplant, they have at least demonstrated experimental viability of inertial confinement fusion. It's only a matter of time before the next generation shows viability of D+He3 fusion and then we'll have even more options.
"Amazing breakthroughs" have notable consequences. This thing has no prospect of any consequences. It is just one number inching past a second number, the second one of dubious provenance.
You may call it a "milestone" if you like, even though it is a milestone on the way to nowhere. The only reason fusion gets any attention is because megaton bombs worked, and already demonstrated Q>1.
People are building out solar and wind power systems that stand some chance of fending off climate catastrophe, each day pushing fusion, like fission, farther from any prospect of competitiveness.

The consequences of a breakthrough are often not noted at the time. It is only when the consequences have happened that we recognize them and grasp the change which has been catalyzed by the discovery. Who, other than Mathematicians, cared about Number Theory when it was discovered?
I don't know enough about plasma physics to characterize this one way or the other, but I think looking for notable consequences is very slippy ground to stand on when dismissing a result.
If there are ever any notable consequences of any value, we can whoop about it then. There are dozens of advances of equal magnitude, in as many fields, every day, without attracting a glance.
