Airlines are not responsible for loss of enjoyment under ec261/2004, or sunk costs.
One sort-of exception is, that if you decide enroute that due to delays the purpose of the trip can no longer be fulfilled, you can request to be flown to point of origin and a refund. But, as OP here decided to continue to WRO and VNO, this is not the case (despite I originally thought so, believing he went back to LAX straight from MUC)
