Just imagine allowing foreigners to come set up picket lines outside your company entrance to shut it down.

That's easy to prevent. All "your company" has to do is move it's operations offshore to the foreigner's land...it's being done on what seems to be a daily basis here.

Some companies probably would. If local conditions get too tough, you move if you can.

That option isn't available to most companies, unless they're in manufacturing. Even then, moving something like a bakery overseas won't work.
