Imagine a new shipping company.  This shipping company only offers a free service to ship a special type of box that can only be used to hold a specific type of object, and that this type of object is worthless (it will not fulfill the ends of any person).  Their shipping service cannot ship any other types of boxes.  Their boxes cannot be used for anything else.

What it seems like you keep saying over and over again is that because the box can be used to send a worthless object to someone else, the worthless object that you put inside the box must be worth buying.  (To make sure the analogy is clear, the shipping company is like the current software implementation of the bitcoin rules and the resulting blockchain ledger, the boxes are like bitcoin transactions, and the worthless objects are like the numbers in the "value" field in a bitcoin transaction output.)
