You Are The Currency
Currency is people much like the mythical idea in the Matrix movie of people used as batteries. But it is more closely similar to Soylent Green.
In the Matrix Movie people are used for energy like batteries -
People have been the currency from the beginning of mankind as people are used, traded, borrowed, sold, bought, indentured, enslaved, pimped, dowry-ed, etc., etc. Coin, cash, and everything else that has and is used as a virtual monetary value, is just a virtual marker for the people capacity value to have a person in essence for various purposes. It is way beyond the energy of the person, beyond their time and skill.
This leads to the case for perpetual debt on people. It is a debt that cannot ever be resolved so that they are owing to someone or something. It is an ever expanding grid that attracts people, then snares them like flypaper to stay attached for continued indebtedness. Self supported energy supplies are few making self sufficiency nearly impossible. Those people looking to separate from the grid are strongly discouraged.

Is it easier to accept that animals are currency than to think of people that way, maybe yes. It is very much instinctive to domesticate living things, but is does not stop at plants and animals, because people too are being domesticated and this has been happening all along. It is a form of wanting to dominate and have power.
Should we assume pet lovers are innocent? Maybe not when you take into account that it is a master over pet relationship. The master (pet owner) has full control over that life, for food, shelter, and many different other things. However, the dominator (pet owner) is also being dominated as a currency without realizing it.
