Indeed. I though it to be relatively clear with “buy” I meant to mostly focus on things we typically explicitly buy with money (for brevity even for these I simplified a lot, omitting that shops are often not allowed to open 24⁄7, some things like alcohol aren’t sold to people of all ages, in some countries not sold in every type of shop, and/or or not at all times).
Although I don’t want to say that exploring how to port the core thought to broader categories of exchanges/relationships couldn’t bring interesting extra insights.
