I don’t have issues with jurisdiction prohibition and that’s why I don’t have to use it. IMHO, there are traders that do that especially those who are living in those countries that you have described.

That’s their only way to access and be allowed to trade.

VPN won’t help you much trust me, if the security agencies of your nation wanna find you; VPNs can’t do much.

I sincerely think that running a dedicated tor node for the purpose will be better than spending money on VPNs.
