It’s an interesting question. And I think everyone has different responses.
Consider:
Do you think blood donations are gross?
Are wigs made for cancer survivors from human hair gross?
What if those wigs are for non-cancer survivors?
Is the traditional practice of using a wet nurse gross (if the birth mom can’t nurse)?
If I use my kid’s baby teeth to make a mosaic, is that gross?
What about fingernail clippings?
It helps one dial into where the ick factor is coming from.
And you hit on something with the “commodity” line. For me, at least, that’s a line where I get kind of wary.
