Suppose I run a company based in France employing 100 people and selling goods by mail order. All my operations are in France, so clearly I should pay my taxes in France.

I don't think anyone would have a problem with that. The problem is running your operations in France, supplying to customers in the UK, but declaring all of your profits in The Democratic People's Republic of South West Nowhere (corporation tax rate: 0.075%) where your corporate headquarters (head count: 1 lawyer (PT), 1 accountant, 3 board members who also sit on the board of 97 other businesses run by that lawyer and that accountant) is based.
