I get why it's so hard to understand, economics (even when studied) isn't really a science and a lot is based in vibes.

Bitcoin is a fascinating example of a modern day commodity based system. Theoretically there is a finite amount of bitcoin that can exist, meaning there is a limited supply that controls the "market". And as we can see in the bitcoin market, commodity has its own problems (most notably people don't really want to spend it).

There are even some research done in the space, I'm not familiar with the Cato institute, but there write up here seems like a decent explanation of gold vs bitcoin - https://www.cato.org/blog/how-bitcoin-system-unlike-gold-standard
