Even if curiosity is a good goal completely separated from application, something I personally do not believe, than it is still worth wondering if the LHC and high-cost particle physics gives the most important knowledge per dollar spend.

Indisputably so, but that is an entirely different line of argument. Which is not, IMO, served very well by conflating it with a narrowly technological cost/benefit analysis.

There is indeed a case to be made that high energy physics and space exploration aren't sufficiently scientifically interesting to warrant the budgets they have, and if that is the case, then evaluating the applications makes sense, because then you need to sell it directly to industry.

But I will maintain that that's a different kind of analysis.

Friends come and go. Enemies accumulate.

When judging spending on particle physics one should as well consider, that a huge machinery will die and it is very difficult to reestablish it. If you stop research now, and in 200 years one would like to restart it, one would have to redo a lot of work and rebuild knowledge, which will be lost.

With ecologists its a special story. First I think that spending for ecologist projects and physics are not at all exclusionary. The spending on science is not so high that a bit more would do any damage to the society. But ecologists really are bad organised. When some astrophysicists had a project in the Adria (ANTARES, listen to high energy neutrinos) they asked some ecologists if they didn't want to participate and put some instruments on the chains to have long term Adria watching deeply under water. They hadn't and that is typical. In physics people usually come up with a huge number of projects once you have some type of large experiment.
Ecologists are not enough connected with each other to lobby for a big project. 300m really is peanuts for a developed world society with a yearly GDP of maybe 30 trillion.

The most important development of particle physics was html, and like this probably spin-offs really will exist in the future. If they are of such enormous reach is unclear, but for more specialised applications it will be good enough.

There was a time when supersymmetric models were all the rage. Now supersymmetry is a requirement to make string theory consistent and string theory is all the rage, so SuSy lives on, even though people have burned the original SuSy papers they wrote in the 1980's.

More specifically, they claim they understand their subject well enough, at a quantitive level, to do detailed prediction and policy prescription, something the humanities in general are very reluctant about.
