But having a pile of money beyond those things "just because" does not really serve the purpose of money: as a medium of exchange for goods and services. Money in itself is not useful, it is only useful for the things it can give you: shelter, water, food, and the various other things as you work your way up Maslow's hierarchy.
At most having a (digital) pile of cash may help you sleep at night (assuming it's covered by deposits insurance). Paying a fee may be worth peace of mind.
