But isn't that also exactly why the whole effort is a bit futile? If it takes this much effort to detect that an event is even happening, you end up describing something that only really happens in a lab situation and has not much relevance for the real world.

That said, LHC cost $4.75 billion that's pretty much nothing compared to the amount of money that gets thrown around in the tech world. So might still be worth it just for the fun of it, even if the discoveries don't have any direct application.
