So it’s made of shit, right? And shit is an animal product. But barring a night of drinking or a particularly aggressive burrito, shitting does not harm the shitter; it’s beneficial and required. Also the animals in question can and do consent, does that make it vegan?
Yes. No sentient being had to suffer and die to provide that product. So replicated meat, leather, or other “animal products” are vegan imo. But I also think concepts like vegan and vegetarian will have evolved in the replicator era.
What about wool and eggs and milk though? These are not vegan but the animal does not die to produce them.
