It is, by definition, NOT debt. With debt, you are given a lump sum of money. These are spending contracts, but any contract has the ability to be gotten out of, unless your lawyers are very stupid.
That would be called a loan, I think?
If I commit to buying some future goods, and sign that I will hand over that money, that's debt. It's money I legally owe someone else. Counting that as debt is totally fair, not counting it is shady as fuck.
If I rent a house, I receive no money, in fact I receive no tangible goods at all really. Just the right to occupy a space under some pre-agreed rules. Yet, I now have debt.
