This doesn’t work for mountain biking, because often the limiting factor is something like frame geometry, which means buying a whole bike to change.
The good news is you can get a decent quality used bike for very decent money, and change cheaper components to suit, things like pedals, seat, handlebars etc are very subjective.
Ride until you break stuff, then upgrade what broke or what’s limiting you. Logical increments is a great way to live imo.
I don’t recommend this with brakes ironically enough
