To me I am buying a superior form of money that gives me access to future optionality. That optionality will differ for people, some want a home, some want a fresh start, some want to buy future hours of not having to work, some want to be able to move, some want to start a family
Fiat gives you a smaller and progressively shrinking optionality window, Bitcoin for me has done the opposite, it gives me time to really consider my options
