My question stands: if it’s that cheap to build, why wouldn’t a big tech company build it? Or a startup? Why does a government need to get involved?

I don't think it's likely to be a profitable endeavor, but it's important and for the public good, so a fine way to spend some public $$

Turning it into an unfunded legal or regulatory mandate for browser companies doesn't seem fair either.
