Get the boat

Yes, as long as the producer consents
- I've often had this silly scenario in my head.
  You walk into a celebrated high class restaurant, and at the bottom of the menu, it reads "Human meat steak. $10,000". You ask the waiter who fetches the chef. The chef comes out and explains that after decades honing his craft, he feels like he's a master of his craft, and now he'd love the honour of cooking a steak taken from his own body. If anyone purchases the steak, a skilled surgeon will remove half a pound of meat safely from the chef, who will then prepare it for you, and the chef is visibly keen to serve this.
  As a vegetarian, I honestly don't feel that this would bother me, if I had money to spend, the only reason I wouldn't go for it is that I'd worry the chef would come to regret giving up chunk of his ass or leg or whatever, and I'd be partially to blame, or that the chef was not thinking straight otherwise.
  Most entertainingly, I think it would be vegan.
  
  This situation kinda reminds me of John Locke talking about slavery. He says that for some rights to be truly inalienable, that people themselves should not have the ability to willingly surrender them, such as by willingly selling themselves into slavery. Now, yes, John Locke owned stock in a slave trading company, so he's a hypocrite in that regard, but I digress. I feel like this is one of those things where people shouldn't be allowed to physically sell parts of their body for consumption, as "not being eaten by other people" is one of those inalienable rights we should have as a society.
  
  I think this is a fantastic thought experiment. Thanks for sharing.
- It actually gets worse.. i saw this post here on lemmy.
  When someone replied to her exactly that, she said she "didn't always consent because she doesn't always feel like it but she does it for her baby, is that still vegan??".
  She was looking for fight imo.
  
  Yeah, she probably was. No one argues against a baby having milk, otherwise the baby would literally die.
- Is roadkill vegan
  
  Did roadkill consent?
  
  How about all the bugs you splat on your windshield?

By definition you can eat and drink human produce and still be vegan. So you could be a cannibal and also a vegan.
- eat the rich!
- Yeah I think as long as consent is given. Animals can't give consent, which makes it immoral to eat them (according to vegans).
  
  The IT crowd comes to mind.
  "No-- he was a very nice cannibal."
- Humans are animals.
  
  That's the point.
  Veganism, as far as I can tell, is not so much about not consuming animal products as it is about not consuming anything that causes harm to animals.
  By that logic, you would keep your child on breast milk as long as possible, to avoid having to switch to cow milk or formula.
- You are what you eat

Well?
- Breast milk is the only milk that can be vegan. It’s all about consent.
  
  Almond, cashew, oat, soy...
  
  Which would mean there's the possibility of this new short horror story I just wrote:
  I noticed two new options in the dairy aisle today: human breast milk, vegan and non-vegan.
  
  So meat is vegan as long as the cows consent?
- Yes, and vegans can also be cannibals for this same reason, as long as the person consents.
- It all depends on if you consider yourself an animal, which, technically, we are.
  
  I'm more animal than most
  
  Only if you define vegan as to strictly avoid any animal product (and define humans as animals). A somewhat looser Definition says to avoid animal exploitation.
  So a product made by a non-domesticised animal in a natural way - e.g. Penguin guano - could be seen as vegan. The animal produces it anyway and the product isn't won through keeping the animal captive and / or "stealing" from it.
  After all I wouldn't be too strict with definitions here.
- You can drink from a well as that just gets water straight from the ground. Which well would be full of breast milk though?

Drinking milk without exploitation, instead of imposing suffering on millions of beings? Get the boat
- What? I'm vegan myself. What does all of this have to do with the post?
  
  Sorry fellow vegan, the post made it seem like human breast milk is somehow worse than or comparable to "conventional" cow's milk.
