That's because you're manufacturing nonsensical delusional boogeymen, rather than dealing with reality.
In the real world, they can't "simply sidestep your country". That's not how markets and taxation work. If they want to do business in your country, they pay tax on that business; it doesn't matter if they are personally living or their company is headquartered somewhere else. And if they do "sidestep" your country, willfully denying themselves profit out of nothing but empty spite and a literally incredible stupidity when it comes to business, they're not a problem for you anyway; they don't do business in your country, so why would their actions be relevant to anything?
