All the legit sites require multi-factor verification, wifi data, cell phone geofencing, etc. Not to say it can't be spoofed, just requires a bit more effort.

When I worked for Amazon in NYC - back before NJ was paying sales taxes, we were told we were allowed to work from home if we lived in NJ, but to say code of something like "I'll be working from Penn Station tomorrow".

Because they didn’t have a presence at that point in NJ?

Cool, tax fraud!

American banks are blacklisted as well, good luck getting around that restriction with a VPN.

Can't you just open a bank account outside of the US?

Yes though NJ you can walk into a 7/11 and fund your account or immediately collect cash winnings from any Borgata casino cage 24/7 https://www.onlinepokerreport.com/
