I don't think OP means 300k cash, but (cash + mix of investments) = 300k.
For all we know it could be 10k cash and the rest investments.
Could be, but regardless, it's very unlikely that his investments are beating inflation at the moment so the point still stands. By holding on to the money its value is shrinking.
You’re basically saying everyone should spend everything in a downtown, and if they don’t they are boring?
