Because having politicians work directly in the Tory part to serve the interests only of their rich donors, their partners, and themselves is so much better than being ruled by elected representatives and those chosen by those representatives (whom you call oligarchs) in Europe?
Perhaps if we hadn't been fooling around trying to destroy the project for cooperation across Europe we could have taken part in making this new legislation better?
I guess it comes down to whether you're willing to accept peace and prosperity above less power for the Tories and a few wayward laws. As we get wayward laws already in the UK (we'd get Art.13 anyway if it serves media conglomerates interests), then it comes down to whether you want to buy back greater power for the Tories at a cost of greater UK poverty, and less international cooperation.
