See thats the thing If you wanted to make Acid you would either have to buy all kinds of chemical reagents and equiptment from a chemical company which would 1. cost a lot of money and 2. the authorities would want to know why you ordered all the reagents and what you are using them for.

The other would be complete synthesis but if you tried to make the reagents necessary you would have to work with extremely poisonous gases and deadly processes.
so it basically impossible.
