Really? Sounds almost exactly how in the 90s restrictions were placed on exporting cryptography, by placing strong software crypto on the US Munitions List.
> Mr. Wilson, 27, claims he spent thousands of dollars over the next two years on lawyers who helped him file paperwork in an effort to comply with the regulations, which are known as ITAR.
"International Traffic in Arms Regulations (ITAR) The regulations control the export and import of defense-related articles and services on the United States Munitions List (USML)."
So why can't, just like with strong crypto, Mr. Wilson place his drawings behind a web form where you certify that you are within the United States and will not export the drawings?
