money can be exchanged for goods and services
Money can't be exchanged for lost time (e.g. due to making money), strained relationships (e.g. due to making money), dreams not followed (e.g. due to making money), etc.
So one has to strike a balance, and doing stuff as a hobby, without making anything money-wise, is a totally acceptable balance if you have your basic expenses (rent, food, etc) covered.
