Also, are you sure this technology would be decentralizing things? Maybe the technology itself would be decentralized but in a world where everyone has an electronic id, I can foresee an internet requiring said id for everything, just like what happens with government issued ids. In turn this would mean that persons would be much more easily tracked across their daily lives. Does not sound very appealing to me.
As for the whole legal empowering side, these sort of initiatives have backfired before so I'm sceptical. For example, once this is in place, wouldn't it make people more vulnerable to being forced to reveal their identities?
