Money was invented to solve the “coincidence of wants” problem (aka barter) but it was traditionally in the form of a commodity which was hard to come by (to resist inflation) so it could also serve as a store of value.

There’s also a difference between monetary inflation (increasing the amount of money in circulation) and price inflation (increases in prices due to normal supply and demand). “They” spend an enormous amount of time and energy to ensure people don’t understand the difference.
