I block advert cookies anyway - manually if new, otherwise it's pre-canned. Firefox also has several ways of pre-blocking adverts and their cookies.
Which I suspect most people do not do. But as noted, it's the user's responsibility to manage browser actions and resonses, not web site owners who have no real idea how their customers will react to their sites across a very wide world web.
