(Just checking we're clear:There is no suggestion that formula should be banned - it's unethical marketing that needs to be banned.)
Bubbles, I accept you are sincere,but sorry, I think you are misinformed about the issues involved. I say this, because you replied with confidence to the OP's question with a totally wrong answer - the WHO code is not law, the UK law does not do anything to back it up still less 'enforce' it...I guess you now realise your error, but you may need to think a bit more about this, and explain why babies in the West should be less protected from unethical marketing than babies elsewhere.
Not having unethical marketing does not restrict people's choice in any way. Formula would still be on sale and freely available. People would make the decision to use it and to select a brand on health or personal choice grounds, not because of packaging, low price, spurious health claims etc.
I fail to see why this is anything but a good thing! It's nothing to do with persuading women to bf - your analogy with vegetarianism just doesn't stand up and this is one of the reasons.
There are many things that are not advertised, without it being an assault on freedom of choice: coat hangers, safety pins, dusters We don't miss it!
