Well maybe the USA shouldn't get those top level TLDs? (Eg .gov or .mil or .edu). What's wrong with them having to use a second level domain like ".us.gov"?
It's been this way for 40 years. Are you a taxpayer? I'd rather not pay for any such retrofit. Furthermore, what makes you think that typos won't be made with any different domain name? Why would a fake hypothetical improvement of the situation drive a massive rewrite of millions of lines of code, server configurations, TLS certificates, specification documents...?
I'm pretty sure the GP's point was that the US shouldn't have .gov/.mil etc, every country essentially has a form of government and military — And besides .gov.us would be more explicit.
The USA gets those top level TLDs because that's who created the Internet in the first place. It's an outgrowth of a US military project called ARPANET.
