The value of a club of our stature, without land, is its league membership. Think how much it would cost to achieve Championship status if you were just starting out. It would be significantly more than 2.1m. That's why I am more sanguine.
Of course this is assuming we have the means to keep Morton solvent and viable. There are plenty of clubs who can't do that, go into debt, and then sell for 1p. We're not in that position.
