I’m a bit confused by this comment.

You state that supply and demand are interchangeable they are not, a classic example would be the elasticity of a specific demand or market.

Then you say that the fed cannot do anything about the supply which isn’t correct at least if you are talking about the supply of money increasing the interest rates can reduce the supply of money within a given economy.

"Supply" here does not refer to money, but to physical goods and services.

A price change by can be caused by changes in supply, demand, or both. Additional information is needed to determine which. In the present situation it seems demand is 'normal' but supply is constrained.

That doesn’t make supply and demand interchangeable.
