For me, the problem with anonymous identities online is that laws (at least in the US) surrounding defamation and other ways to regulate human interaction seem based on a real identity. Without that, I'm not sure how those and similar laws can be enforced on the internet. One could argue that they shouldn't be and that's maybe a separate conversation, but for example, right now, if someone defames me in person, I can sue them and if they defame me on the internet under anonymity, and I don't think I can (yes they can be anonymous in person but I think it's much more difficult).
