anon for this,
Firstly, please explain how we can use skins of animals for Mitzvos without torturing and/or killing them? Are we to look through the forests and find animal corpses with salvagable skins on them? Or maybe “Give me a break” will tell as that there are some shitos that allow human skins to be used?
You say that there is an inyan of eating meat… because of simcha. I am not arguing if that is the reason or not as I am not even sure. What I do know is that the reasoning behind it would make a difference. If you are refraining from eating meat because of health reasons or because you don’t like it; that is one thing (even though there are people that eat a tiny drop just to be yotzei but that’s a different point..) But if you are refraining from eating it because you think you are above the Torah and have more logical morals, I highly doubt that is an acceptable reasoning.
