2008 is remembered by most through phrases like “trickle down economics” and “bailouts” to the irresponsible men who built the house of cards, including “golden parachutes”. In other words, whether reasonable or not, a very large number of people don’t feel great about how our flexible monetary supply was made use of. Bitcoin is literally a direct reaction to that (e.g. view the coinbase for the Bitcoin genesis block).
Newer cryptocurrencies have more sophisticated governance structures than Bitcoin (see: Tezos). Some of them could allow for an elastic monetary supply. The downside of these systems is that it takes a lot of work to properly encode the specific set of rules which decide when to increase the supply, and how to distribute the new supply. The upside is that these rules actually exist and are unambiguous.
