Creating such a vacuum is not the issue. But keeping it stable over a long period of time without using vast amounts of energy is impossible. At least as long as materials have certain properties, maintenance is a thing and you apply real world physics. Why do you have to focus on that one metric for you proof btw. there are hundreds of scenarios that make this unviable other than the type of joints you're using.

Because as you have pointed out there are real engineering challenges you can talk about.

So why lie about a benign problem that already had a simple solution?

That's what I take issue with.

That one flaw in some videos you watched doesn't render the entire criticism invalid.
