Is this supposed to be a counterpoint? Goldwater was saying that the endeavor would use public funds on a far off vision at an unknown but spectacular cost (for the time). He did this at a private event paid for by willing participants, I’d reason some of whom disagreed with him. If you’re saying that expensive plate dinners and perhaps lobbying more broadly isn’t effective, I don’t think that’s correct. Otherwise, this comes off as conspiratorial, not at all reflecting the thoughtfulness of the rest of the post.
