Thinking abstraction is nonsense is a big mistake. Money is an abstraction of energy, as are electrons, nutrients, and the blood cells in your body, and the food you eat. The force you work for, by denouncing all that is creative and good, is an emergent property, an abstraction you can't know about, because you want to believe abstraction is a harmful device created by humans. It does exist, and it is physical, and it actually wants you dead, after you've finished being a most useful energy slave to it :)
