Of course you can: you can tax phones until most people can't buy new ones. That's what will happen once these laws are imposed and people keep buying new phones because they don't give a fuck. 100% democratic!
That's kind of what is done in France as well actually, there's some subside for repairs and I'm pretty sure the money is taken from a tax on new phones.
That's not too significant yet but I'm expecting the amounts to increase
