Not sure how the salt is relevant, except to say that in Roman times the soldiers were paid in salt, that is where the term salary comes from,I suppose that we are all collectors of one sort or another, we only have to look around us to see the debris we all seem to have, Books, Videos DVD's etc, quite often not read or viewed, totally worthless yet we are unable to let them go.
If I look around my workshop I see tools I have had for years, and many I cant even remember the last time I used them if indeed I have used them at all.I suppose its in our nature to collect, to have belongings, and to want more, sometimes we get quite fanatical about our collections, despite the cost or in fact despite the practicality of what we collect.
We could ask is it sociable to be an avid collector of anything, do we create jobs by collecting, do we deprive others by collecting.there are different ways of looking at collecting, I am sure we don't always approve of people collecting data about us, yet we always seek to gain more knowledge about people in our everyday lives.we like to collect information but we don't always approve of others collecting information about us.
Are there people who have turned their backs on civilisation, don't have phones, TV's and live in isolation, and yet can claim that they don't collect things.
Collecting things in my opinion not necessarily a bug, just a normal part of life.
