EU should consider this hypothetical: Imagine that aliens from a remote galaxy came to Earth to trade. They sell alPads and alPhones. They don't have any papers about how those were created and what kind of costs they paid in their galaxy. It was so long ago no one remembers and why would it matter anyway, maybe alPads and alPhones grow on trees in their world. Now consider how we would like to tax those. Is VAT enough? If not maybe tax for land where they open their office? Whatever you decide do the same with foreign companies in Europe. It's the only way as digging into costs/deals in other countries which may not even be friendly with EU in the future doesn't make much sense.
