On a more serious note though, those use cases are real and specially useful on totalitarian countries.
Moreover, even in today's most free countries there still is money debasement and control over what people can buy.
Bitcoin enforces absolute scarcity, something unprecedented.
You know that we are in a centralized world, where everything you so from childhood till date is recorded. The day you came to the world, the school and houses and everything that you do in your country that involves the government is recorded. This is why initially when bitcoin came into existence there was a strong force fighting against it because they see that it will limit their power on citizen financial lives. The government love to be in control of their citizens so that they can manipulate them in one way or the other.
However, it is not everyone that understands the benefits of decentralization and that is why, you see that some people will not adopt bitcoin because they only believe on what the government created and they think that whatever is not from the government will fail. Some people that bitcoin is still illegal in their country, they are also scared to adopt it because they don't want to to go against the law, so that they don't get jailed because they lack the proper knowledge of what decentralization is.
From a philosophical point of view I would say that in a decentralised world, all transactions that you will ever make are effectively recorded and not only in one place, but in a million copies of the transaction register.
Look, decentralisation is not that helpful when you live in a country that lacks the basics freedoms. Cryptos are not a solution to every problem out there, certainly it helps totalitarians and not alike.
