Thanks for posting the floor plans of it. Now can you explain what the value is of the configuration of the telescope in question?
As far as high costs go, you should realize that costs are relative to what contractors and workers charge for their labor, materials, and services. People want to make a lot of money so they can afford all the expensive things that are available to buy in the world. Then, because they go out and buy them, the environment gets slowly destroyed/developed and other people make the money they spend so they can go out and do the same thing.
If people would build these elaborate telescopes, etc. without asking more than a poverty wage for their contribution, they would cost significantly less. However, there's still the problem of putting them in a sacred natural area and creating roads and traffic through the area to build and use the telescope. What is the benefit of such telescopes over what orbital telescopes can produce?

It doesn't need to draw a big crowd to make a lot of money. They will just charge a ridiculous usage fee and rich donors will contribute large amounts of grant funding for high-status astronomers to visit the telescope. In other words, it will be a very elite place to go. You already said yourself they've got a half billion dollars just to build it. It's a business deal and often such business deals are well-funded because they establish precedents for developing previously-undeveloped areas. It's sort of like all the sleazy men betting on who can deflower a virgin because doing so paves the way to more sexual abuse for them all to enjoy.
Why not just leave these sacred natural areas sacred and try to restore more of the already-developed areas to a more pristine state. When they finally figure out how to develop an area without offending those who want to preserve sacred undeveloped natural areas, it might be possible to build such telescopes in a very non-intrusive and unobtrusive way, but I don't think we've mastered that skill quite yet.
