it doesn't make sense to remove it, because i can simply create another wallet if i want more anonimity, and creating another wallet is more anonymous than making more address with the same wallet
not to mention it also lower your average transaction size, it's a win win situation, for everyone using bitcoin
True, and all that making people keep the same address would do is either to create new wallets or to just move to a more anonymous cryptocurrency, like cloakcoin which some people seem to like.
Countries will decide whether Bitcoin should be legal or not partially based on their commitment to privacy, but ultimately no one can
entirely ban something on the Internet unless they entirely remove the conventional Internet for their own purposes (e.g. North Korea's intranet), and by compromising its principles Bitcoin would leave itself vulnerable because if a government decided to ban it, people would find it much harder to hide their use.
