I mean, you're just reciting the arguments that the science establishment generally recites. We have spent tons of money on particle accelerators to no clear benefit, either to science or to society. If a similar amount of money had gone to SETI, many of the above objections would have been addressed and resolved, with the advantage that science is being done which the average person paying for it is likely to a) understand what is being asked and b) be interested in the answer. |

Particle accelerators have exploratory experiments like hunting the Higgs boson with LHC but they run lots of other experiments as well. There's also lots of particle accelerators (of varying capability) around so if you devise an experiment needing one you likely have several options unless you literally need the LHC.
With large telescopes there's far fewer available and the sky is pretty big. Radio SETI is a long shot search and optical SETI even more so. It's not that they lack merit but getting funding for telescope time is a lot harder when the chance of any positive finding is very remote. A lot of SETI funding actually piggybacks on other research using the same telescopes.
The chances of SETI finding positive results isn't necessarily from a lack of things to find but from physical limitations. Our best radio telescopes could only detect Earth's more powerful radio emissions from a few light years away. Broadcasts like TV and radio wouldn't be detectable outside the solar system. The inverse square law is a stone cold bitch for interstellar communication. SETI's best hope of finding signals are ones intentional ones.
Even with billions of dollars SETI would have similar chances of detecting an ETI as without. It's a needle in a haystack search with warehouse sized haystacks. More money doesn't necessarily get it done much faster or better. There's a limited number of sites for large radio telescopes and they have limited fields of view and stars are only in that FOV for a limited time. More money might let you search the warehouse sized haystack a few times faster but it's still a vast search space.
