SIC is used across the government. I ran into it in my work because the USPS uses it, and I was working on software that implemented a couple of their change-of-address matching systems.

Having said that, if you step back a take a wide view of the situation, it's obvious that the 20th-century regulatory bodies are incredibly obsolete. I argue that they always held us back, but now it's something that even a child can see.

For example, check out Paul Romer's writings about the FDA's role in helping the Coronavirus spread: https://paulromer.net/fda_perpetual_process_machine/

(Note that Romer is a co-recipient of the 2018 Nobel Prize in Economics, not some crank.)
