...my comments were confined to a subject to which I feel that the definition of "obsolete" within our hobby should not be tied.

I know that no one's asked, and probably no one's the least bit interested, but my own personal definition goes like this (regardless of jurisdiction):

If a casino had a chip in the cage and would, by policy, sell you the chip, then it's NOT obsolete. Everything else IS obsolete.

Those sold-out commemoratives at the Hard Rock... they're only obsolete if they've been demonetized. The Caesars Palace $1's that are not being used on the tables are NOT obsolete, because you can buy them at the cage. The beige 50-cent H-mold with the gold inlay with Caesar lying on the bed, however, is DEFINITELY obsolete, although they have not been demonetized. The Atlantic City Playboy chips are obsolete, beacuse there's not a cage in town whose policy is to sell them if they happen to show up there. The "TTSS" chips that might currently be in use in various Sacramento cardrooms are NOT obsolete, even though the casino of issue might be closed.

This, of course, is only my opinion, and I'm not in the proselytizing business. On this issue, there are probably as many opinions as there are collectors, and until that time that an "official" definition is adopted, there's no "correct" one. I just don't think, however, that what the U.S. Government deems to be the legal possession of a casino chip is germane in this discussion.
