O.k.  I understand that the some prices are more subject to negotiation than others, and if you are in a retail store, sometimes they will be wiling to take less for products if you make a reasonable offer.  Of course, a private sale between principles who have the authority to bind the terms will have more flexibility, if they are willing, and when push comes to shove, some terms might be more flexible than others, and perhaps, you might be willing to give a greater value to legacy (non-segwit tainted) coins? But, likely in the end, if we negotiated all of the terms except for whether payment would be by legacy or segwit tainted coins, you may well recognize that the coins have the same value and are likely to have the same value for quite a period into the future - and there may even be times in which segwit coins are going to have more value because they have more flexibility in terms of lower fees, faster transaction times, lightning network compatible and perhaps some multi-sig and other programabilities.  For the sake of this argument, you might posture that the value to you is different, but you have already admitted that you would do the same price in the earlier referenced post.
