Begging the question. Why do you assume it was done intentionally? Did anyone from m NASA admit to destroying footage on purpose?
None of the articles about it stated "Ooops our bad, it was accidentally done". What's worst is why was it the most important, most critical piece footage(classified) in NASA history destroyed and not something less important. Not only was the footage destroyed, NASA tech was destroyed as well. No one's bats an eye, no cares.
Again, begging the question, alongside a strawman.

No one is arguing that technology was "far greater in 1969 than today". NASA's budget was much bigger back then, and they actually had a supply chain built up to prioritize going to the Moon. Many diagrams for mission critical components weren't owned or controlled by NASA; they worked with aerospace engineers like Boeing to engineer proprietary components for the shuttle. Boeing doesn't manufacture those parts anymore, and has no incentive to. The computer technology of 1969 is also completely incompatible with technology of today. Those statements would have to be massively upgraded.
NASA admits they have no technology to get back to the Moon. That's is who is debating it. However they have the tech to go to Mars as NASA claims.
Boeing isn't doing what?

NASA works with dozens of other companies as well including DOD for projects so why is there an real issue with budget?
Many different reasons why we could go to the Moon in 1969, but we can't now.
Again what are these reasons?
