The problem I have with producing thin stock in my shop is that I have a thickness planer and no drum sander.
1/8 inch scale stock often does not survive the thickness planer - even with sharp blades, stock double-sided taped to a backer-board, and a light touch on the thickness adjustment.
A basic, table-top Jet drum sander is more than $750.
I am grateful that others can provide beautiful, perfectly smooth/flat stock at a reasonable price.
