And I quote, "According to The Pegasus Foundation, an organization advocating to ban donkey hide products, an estimated 8 to 10 million donkeys are killed and skinned each year to meet demand for ejiao."

Clearly, most of the 8 to 10M donkeys killed are not endangered. There are 40M donkeys in the world.

Just eat the non-endangered kinds, and may be captured some and domesticate them. Problem solved. And yes, it is no big deal.
