The Rashba (and Ramban [Rav Moshe ben Nahman. Nahmanides]) held a document is not money.
See the nook of the Rashba on Tractate Kidushin page 5 and also page 47.
You see this in Kidushin and Pidion HaBen. The question that Rav Shach brings is from Bava Batra where the Rashba apparently holds a document of obligation should be considered as an exchange of money. [This Rashba is not the same one called the Rashba in Tospfot.]
The actual subject is famous. You have a cases where a slave is owned by two owners. Then one lets him go. So now he is half slave and half free. Now a slave becomes obligated in all commandments when he is freed. [As a slave he is only obligated in commandments that a woman is obligated in.]
The question to the House of Hillel seems clear. He works for himself one day and then the next he workers for his owner. It goes back and forth every other day. But the students of Shamai asked but what about getting married? He can not marry a fee woman because he is half slave and he can not marry a woman slave because he is half free. So the owner has to let him go and the slave writes a document that he is obligated in the amount the owner is losing. The Rashba holds this is good. But why if the document is not money?
Rav Shach answers this in this way. The reason you need more than a document to be counted as money in terms of Kidushin and in businesses deals is that you need a buyer and a seller. For example lets says one would give money so that a field should be "hefker", well that would not work for this reason. But freeing of a slave is "pedia" letting go, or redeeming. It is not a business deal. Once the owner lets go, even if the reason is simply that he got a document saying that the slave will eventually pay him back that is enough.
[Actually this subject may not be famous since clearly Abraham Lincoln was unaware of it. Detroit would look different today of only Abe Lincoln had learned the Avi Ezri of Rav Shach.]
Why you can ask is this just when freedom is so important? Because everyone has their place and ought to fit into their place. Obligation is part of freedom as Hegel goes into. See his discussion in History.
[The reason this same reasoning does not apply to pidion ha'Ben or Kidushin is clear that in neither of these last two case do you have a חלות state of being that is already here in potential but just waiting for something to trigger it so that it can become real.]
