They aren't gone forever until the loss is realized. Creating this replacement really high risk, really high reward position. If the new position stays at full loss, then an extra $2 has been thrown onto the fire. But if the share price comes back, then all of that leverage recreates the original position and recovering all (as much as you want) of that loss.The money/shares *are* gone forever. You'll always be down by that $28 whether you make $1 or $100 in the future. Trying to "recoup" the loss by spending $2 to return an arbitrary $28 probably means losing $2 on top of everything else. If the $2 is meaningless, that's fine. But if $2 is material and you'd never invest without the prior loss, I don't understand why you'd make the trade now.
The job now is to make the best investment decision today, irrespective of what happened in the past.
The key difference in this specific instance is that the spread relationship enables bringing the spread a LOT closer to the current share price, and doing so nearly for free. That's the edge that turns a big loss begging to take some more with it, to a position that has a reasonable chance of being OTM in a couple of months. That specific big "free" leverage is why you spend the $2.
