Well my point is that "actual market value" is not an objective definition.
So in the context of "trading" being discussed here, the only way to assess a market value is to list the players at $1, then see where the bidding ends and let the 2 guys go ahead with the trade at the values reached on the market (plus cash from one side). If they can't, the winning bids get the players. It shouldn't really be left to anyone's judgment.
Again, that assumes that there's not someone bidding outrageous amounts (either because of money transfers to friends or because they're quitting). If a 19yo announcer potential guy with 24 TSP is listed at one dollar and there's a bidwar for some unknown reason that raises the price to $500k, the seller is not in the long run going to get to keep the full transfer price and should definitely self-report that.
Anyway, we have rules. We have people who are here to interpret the rules. We have the appeals process for those who dispute the application of the rules. We generally don't discuss much more than that in public.
