This would heavily encourage exports and disalign the company's incentives with the nation's.

I do, however, this could be a good idea. But I think the true issue is that we need a globally unified tax framework (and serious retaliation if a nation decides not to adopt it).

100%. All of these schemes depend on the existence of a jurisdiction with low (or non-existent) corporate taxes that they can shift profits to in order to avoid paying taxes in the actual jurisdictions in which they manufacture and sell. Doesn't matter whether at its core it's a transfer pricing scheme, an IP royalty scheme, or a thin capitalization scheme. You need a man (country) in the middle with low/no taxes where you will recognize the profit you don't want taxed.
