You are bringing up a very good point. We will build the solution to this - we will incorporate in different countries, and offer to take care of the legal part as a service. Then it is real employment and not freelancing like on other platforms.
It makes a lot of sense to allow people to work together regardless of where they are based. So someone needs to build the solution to make it easier/better.
Btw, Remote work doesn't have to be across countries.
