Excuse my ignorance. But is there truly any way a currency can be completely decentralized? Sure, maybe not central to a governement, but some central entity will always lay claim to any currency. It's further unrealistic to believe each government won't regulate cryptocurrency at some point. I have the same question about dapps and a dectralized internet. Again, I apologize if I'm missing a fundamental factor when asking this question. However, I'm not too proud to ask and be educated.
Decentralised currencies are unregulatable by nature, since there is no regulating body that governs them, except the built-in protocol which drives them; this is a bit more fuzzy when you start talking about DAPs, because they are run like companies. However, the underlying cryptocurrency must strictly adhere to it's ungovernable nature, or it will lose value due to loss of investor confidence.
