Sorry, but law works a certain way and it isn't always easy for the average person to understand, so I'll try again.
If you look at the laws governing beer production in Indiana you will see 3 different definitions. Commercial, craft, and personal use. The law as written applies to commercial production. Craft has their own exemptions and specific other regulations. DIY (personal use) has its own exemptions and specified limits. So, 3 different defined producers and 3 different regulations.
HB 1432 has one definition of juice production, commercial. Thus all juice production is considered commercial under the law because nothing else is defined and nothing is excluded. If it did not include DIY then DIY would be defined and limits set to differentiate DIY from another type of production.
Since DIY is NOT defined, NOR specifically exempted, it is the same thing as commercial production as far as the agency is concerned and the only definition a court could rule on.
Just because it isn't included, doesn't mean the law doesn't apply. Laws on murder do not include redheaded step children, but if one murders one it is still murder. And if a redheaded step child murders a non-redheaded stepchild, the redhead is still guilty of murder.
Does that make it make sense now?
(I keep seeing the confusion on DIY for this law and it seems to orbit the fact that DIY isn't specified, but commercial is, but that just means that any juice production is commercial juice production in the eyes of the law. Common sense doesn't apply to laws, nor hidebound ATC agents.)
