You want something that makes absolutely no sense? An agency I never heard of has abruptly and without explanation has disallowed private registration of .US domains.
They have this authority how?
They did this unceremoniously why?
Let’s see… for government we have .GOV, so .US can’t be needed for that.
.COM, .NET and .ORG are worldwide and give no special indication you are someone from the United States.
So yeah, that leaves .US as an option for folks in the US who would like a domain that identifies them geographically. Great.
