And how much does that cost? I bet it's more than 5 cents.

Not by design, that's an implementation details that can easily be changed in the future if 1 sat starts to become valuable enough to make a difference.

Do you have an example of a single commodity in the history of humanity that simply stopped being traded because it became "too valuable"?
I can't even understand how that makes sense, if it's valuable some people will want to sell it and get something that is more useful to them, like a house, a car, whatever. People don't commonly decide to hold an asset until their death bed.

What happened to Gold?
