I don't find it at all desirable that some people have the right to devalue my holdings. It is farcical to think that people would hold the medium of exchange forever if it kept increasing in value because at some point they would either have so much that they would prefer to convert (some of) it into material wealth or chase something with a higher rate of return. Alternatively they would have so little that they would have no choice but to convert it to survive. You cannot eat the medium of exchange.
