The word "use"(spend) is the key word of concentration because it seems people talk so much of savings as if one isn't supposed to use their saving even until death and I began to wonder what the purpose of saving really is.
Nope, your interpretation is too limited. Why not continue with the next part of the article [1]?
Saving money can also help us cover unexpected expenses, such as an illness, replace an appliance that cannot be repaired or make an emergency trip.
Actually the source of the article detailing the concept of savings is better than you think. Adding mine, setting savings to be flexible won't hurt you financially. I control my money, not the other way around.
