Your commenting resemble the libertarian cat paradox: expecting the world to be set up for your benefit to do whatever you want.
I don't know about parent, but I don't want to be forced to gamble on the stock market or to become a landlord simply to save the fruits of my labor. In an ideal world I could have used gold for savings, but gold already lost against fiat and people are looking for something better.
> but why should society care about you by creating a synthetic store of value for you?
That's the beauty of bitcoin, society doesn't have to care about it, bitcoin just does everything on its own and grows naturally.
The only way to get what you want is to physically save the goods and services you want to buy in the future, but obviously that is impractical. Hence, society, markets, money, and inflation or deflation to balance the supply and demand of goods and services.
Imagine a world where everyone is your age. You and everyone around you works and is productive. You're saving money. Then, you all retire around the same time. What value does that money have? You all have money, but there's nothing to buy with it. This is obviously an extreme example. But what you want is also extreme: that population and productivity are constant over time.
Aristotle would have disagreed with you, and today's market seems to disagree as well.
