Bartering

[Highlander]

Thats all very good until you desperately need something yourself,..lets say a member of your family goes down with something, and you need some sort of medicine,.. bartering something someone else wants might be the only way of treating the person

I can see what you are saying,.. but at some point we will all run of some very important goods, that we will probably need to replace,... bartering might be the only way to go a few months or years down the line
