Ah, you remember "Ectopia". That's a golden oldie from the Eighties!
"Ecotopia" but I like your spelling better.
As far as this idea goes -- have at it! But they will get zero US dollars for that time. And zero US federal personnel and no Federal courts, no border patrol, no subsidies, no Section 8, no WIC, no Food Stamps, no nada.
That would be great. Maybe they can convince Oregon to join 'em! The result would make Bangladesh look like Beverly Hills!
