They will require special licenses for machine shop tools in response eventually.
Think they won't?
I'm an organic chemist and the stuff that I use in lab that requires special approval to get from the DEA is ridiculous. For instance, benzaldehyde, a very common chemical, is regulated, not that I couldn't find a way to make it from toluene if I wanted to and if I were making illicit drugs. As it is we have to file paperwork and store that and iodine in locked containers.
