Your point is technically correct that the card and gun alone does not per say make you a prohibited possessor.....takes a couple more steps. However, a card and a gun = probable cause to get court order for "medical" records. It may take a little leg work but not rocket science to locate where a person bought their dope if using the card to purchase from "licensed" dealers. Once you have the record of their "prescription" being filled the case is made....especially if you have numerous fills.
To the other point. If you once used in the 1950's and quit you are no longer a "user" (distinction between use and user). "User" refers to an active user and is somewhat "fuzzy" as I mentioned above. How much current use makes you a "user" is part of making the case. Same as duration between use. All goes to the issue of evidence.
