Sometimes laws are not just and governments are not aligned with their people. Some examples:
sci-hub is not legal in most jurisdictions despite its immense positive benefits. Since being deplatformed, their primary means of receiving donations has been crypto.
Then there are the unplatformed (from a global transactions perspective), where the cruel realities of poverty, scams and fraud means the majority are punished as collateral damage for the actions of a minority. Poverty means a cost benefit calculus has deemed fine-grained distinctions are not worth it. I can understand the justifications but still feel it as deeply unfair.
When social media are used to highlight and organize protests of corruption, extra judicial killings and more, governments will ban social media and block the financial accounts of anti-corruption organizations. Coupled with being in countries where global transactions are already high friction, crypto provided real benefits.
A non-crypto example is having to use VPNs to access certain university websites because its administrators subscribe to a lazy service that has blanket banned IPs from certain countries.
Not unlike Tor, it's one of those things whose main use is by criminals in sane regimes but a high positive option in despotic or oppressive ones.
