Of course the problem with the "compensate me" arguments is that a lot of people were going to make decisions that would have turned out poorly yesterday (indeed, the market is balanced and every transaction has a counterparty), though of course with the amazing clarity of hindsight few would recognize or admit that. So if they need to compensate for illusory lost trades, do some people have to pay them for losses they would have incurred?

[I get that there are some complex options that can legitimately be all downside when trading isn't available, but that's a less common option]
