If the goal is to slow takeoff, then ideally you’d have some way to taper up the fraction destroyed over time (as capabilities advance and takeoff might have otherwise gone faster by default).
Separately, you could presumably make this proposal cheaper in exchange for being more complex by allowing for CPUs to be produced and limiting the number of GPUs produced rather than requiring GPUs to be destroyed. This only applies at the production side.
