You are already required to register for VAT as a non EU company and that’s one of the many ways in. By that logic, any EU company is also subject to the tax laws of every other jurisdiction in the world, whether or not it has any presence there. No doubt the governments of all the other countries seeking to impose sales taxes and the like would be in favour of that. Anyone hoping to start a small business selling online would probably take a different view, though, so if you want people to be able to start new businesses, your national governments in the EU had better be on their side on this one.
