I'd rather sell 100% at 10x the cost than 10% at 10x the cost. What's the benefit of deliberately reducing demand? Why not sell 10% at 100x instead of 10% at 10

I'd rather sell 100% at 10x the cost than 10% at 10x the cost. What's the benefit of deliberately reducing demand? Why not sell 10% at 100x instead of 10% at 10x by producing something that actually appeals to more, and is desirable by more?
