>If you have $10 million in the bank, you're not just a "saver" or "refraining from consumption".

If an economic agent holds a money, they are -- by definition -- saving their money. If they instead decide to speculate with the money "Hmm I think gluten-free bread will be in higher demand next year, better buy ovens today, to sell to the baker then" they consume scarce resources (labor and materials to make the oven). If they invest the money in a business endeavor "Hmm I need to allocate capital from money to wheat, ovens, to turn a profit as a baker to produce bread" they consume scarce resources. These capital allocations change the exchange rates of these goods.

Try as you might to avoid it, all forms of punishing cash holding induces undue consumption.
