I was thinking the same as OP's thoughts on bitcoin but with fiat a while ago.

I was thinking how a group near me that offers extra curricular activities to children of school age (things they wouldn't get to do in school) now pay a fee of $300 for a yearly membership and I was pondering if the club would survive into the coming years if they don't raise fees and costs go up and then I remembered inflation was a thing because 20 years ago the same membership would cost you $100 for the year (prices converted based on today's exchange rates).
