Lost coins are overall good for the market because the maximum supply is much lower and with lower supply and ever increasing demand it will eventually create this artificial scarcity that would raise the price of whatever is on demand which in this case is bitcoin, now that's the perspective of the whole market excluding the person that has lost those bitcoins. I don't even think chaos would even ensue, there's no way that you have been in this market for a long time and you still don't see how chaotic the market is? Bitcoin is a volatile asset that could just dump overnight without any reason or pump for the same thing, that's already chaos OP, no way that bitcoin could get more chaotic than that if you ask me.
