I find it quite an assumption that we could quickly form a company and build a consumer-usable platform around our project. Rust has some very specific needs that don't map what the general audience needs.
Also, our tooling doesn't need to be excellent, it needs to work. A lot of our tooling is surprisingly unsophisticated at close look. That's fine in an org that knows the limits, but it would hit the ceiling quick if you'd try to generalise its use.
