If the public sector has the "right" to take from Vodaphone, Starbucks & Amazon, by force, thay have the "right" to take from you by force, even if you've got nothing. That will be no excuse.

The public sector has the right to tax Vodaphone, Starbucks, Amazon, Boots, Top Shop and hundreds of other thieving multinationals, because those corporations make billions, while barely contributing to the educational, healthcare and transport infrastructure which help them to make such astronomical profits

The multinationals do NOT have any reciprocal "right" to take from anything from anyone - the only thing they have the right to do is to offer people their goods and services (assuming you're not just some right-wing libertarian troll, all you're pointing out is in fact the weakness of approaching this issue from the point-of-view of Victorian-style "classical" [ie - anachronistic] Anarchism)
