So, if a letter or document that nominally or presumably conveys the signer's "intent" or intention to buy, is essentially meaningless and worthless in legal terms, and is not binding on the signer or anyone, and CANNOT be enforced on him, then why would a respectable crude buyer, in the first place, want to waste its precious time and resources (or that of its expensive lawyers) to engage in such a fruitless exercise for the benefit of a seller? Especially for an unknown or obscure seller?
Moral of the story? If you're ever contemplating using a Letter of Intent in a business transaction, you had better watched out, it may not be as simple a matter as you might think. You better be very cautious, for it could result in unforeseen and unpredictable consequences!
