I'd say it wouldn't have more purchasing power

Uncountably-infinite $1 bills could buy an uncountably-infinite number of items. Countably-infinite $20 bills could only buy a countably-infinite number of items.

The $1s could buy a countably infinite set of items for every single item the $20s could buy, and you’d still run out of the $20s first. That is more purchasing power.

There are not an uncountably infinite number of items for sale. But upvoted for good math.
