That's like saying movies aren't imaginary either because there's blu-rays. Even if we take that point at face value though, the vast majority of money is imaginary, only existing on ledgers. When the fed "prints money", it's just adjusting an entry on a database somewhere.
The vast majority of money is not physical, by likely 2 orders of magnitude, so you cannot touch it. It's a value in a ledger that can be moved electronically (or copied by hand).
