I don't deny that my idea will result in some degree of protectionism. I think that's worth it in this case in order to prevent the flight of profit to tax havens, but there are absolutely edge cases where it forms some barrier to free trade.

On the other hand, having pure profit in a foreign market without any costs there, doesn't sound like a terribile position to be in. And maybe local businesses could use a bit of an edge compared to multinationals.
