Maybe because the country took/got the name almost 800-900 years before the state of Georgia existed.
I thought that Georgians called their country Sakartvelo?
The real question is if there are any Georgian Georgists.
yes. there are dozens of us.
"Georgia" is based on the Persian name of the country, and its similarity to the name of the US state is coincidental. For some reason, the Persian name became more popular around the world than the native Sakartvelo. Or the Greek "Iberia", which shares its etymology with "Georgia".
