You live in a more progressive society than me. I literally this year alone was almost in a conversation where people were in agreement that Bitcoin was only used by money launderers and cocaine drug lords. They were not being funny, either. They were top-of-the-line highly-qualified finance people with decades of collective experience and education. I just shrugged and said "you're right".
Those are actually excellent use cases for Bitcoin, and may it never be stopped from being used for moving value across countries illegaly, and for buying drugs from the dark markets. The moment the authorities can stop Bitcoin from being used for illegal activities, is the moment Bitcoin has lost its main value proposition.
Indeed. Use case is use case. In fact, governments trying to stop Bitcoin (I'll always remember the US sanctioning of Bitcoin addresses and how that actually led to more anon donations going to those addresses as a funny case) only proves Bitcoin's main value proposition, as you say. Marathon is only the latest to realise the folly of trying to stop/censor any part of the network.
