So Apple might have $100B stuck in Ireland, unable to bring it to the US, but it doesn't matter, that money still counts for their shareholders.
And it's the same thing here. If you try to tax $10B they'll just have 100 companies all making $9.9B/yr, in a variety of different countries, completely separate from each other, and you're back where you started.
And while this would be extremely complicated/expensive for them to manage, it'd be profitable because the alternative is to get a 100% tax on those profits.
Taxes aren't easy. And calling a company that sells phones a "society-destroying problem" is a bit hyperbolic, don't you think?
