It seems likely that this indeed will give you increased security.

But it is dangerous to educate non-technical people that this VM-based OS gives you absolute guarantees of security.

And please don't start redefining the term "air-gapped" such that it applies to a VM that doesn't have network access. "air" "gapped" is a pretty absolute concept, and does not mean a VM without network on a host that does.
