That's correct. The idea would be to make the supply stable wrt. to the hashing costs. Meaning supply would increase with increasing computational efficiency and stay constant relative to it (ie. the inflation of this currency would be tied to improvements in chips).
Anyway, the point is that from the beginning bitcoin was set up to promise massive gains to early adopters, which helped gain traction. Your suggestion has nothing similar, so it's not clear why anyone would adopt it.
Really, it seems like you're promising hyper inflation (because of Moores law), which is something a lot of people flock to crypto to get away from, and nobody (even those who like a little inflation) thinks is a good idea.
Incentivizing spending rather than hoarding just means you hit the lower bound (probably zero, unless receiving units of your coin is really, really technically interesting to some people) earlier...
The general lack of awareness of how traditional currencies are established and maintained is just shocking.
Also, make sure you understand scalability. As much as the crypto community likes to poo poo the Visa network; the Visa network handles an order of magnitude more transactions per second than the current cryptocurrencies can handle.
It isn't shocking. The point of 99.9999% of all cryptocurrencies aren't to make anything useful. They exist to get the creators rich. All of the rubes that buy into these scams will simply be sending their former wealth through a massively inefficient rube goldberg contraption that lines the pockets of those at the top of the pyramid.
The creators don't need to understand monetary policy, economics or scalability. The creators just need to understand enough deceptive marketing to get some suckers lining up to buy. The smart ones also know just enough ways to pocket their newly acquired fiat wealth and escape without getting caught by jonny law.
Visa network is centralized and owned a company. Bitcoin is a protocol with no central ownership. Additionally, visa network is currency-agnostic and enables payments in any currency they want to support. Centralized services like Visa can work with Bitcoin in various ways, for example the settlement transactions can be done with Bitcoin.
Additionally Bitcoin has been developed from the start with various centralized services built around it - without those services it wouldn't be popular at all. Any centralized service can scale as well as Visa. Though where Bitcoin provides value is not near retail payments, and while there have been bitcoin-reloadable visa cards I think that is not very interesting use-case.
Where does it provide value? If it's bad as currency, what's the use case? It certainly fails store of value test (unstable, high volatility).
Now, if instead of using some uninteresting hashing, you did genuinely useful work to create the coins, perhaps like gridcoin, then your system might make sense - since it's representative of an amount of computation performed.
Nobody in their right mind would hold it though - I presume you'd use it to pay for other computation, and there'd be a market of companies wanting to buy it in order to get their workloads computed.
Two issues: 1) This scheme would only work with a PoS algorithm for block creation, because in a PoW system the security depends on the block reward (which would be low in this system). 2) There's not really a lower bound for the price of this token - the intrinsic value depends on it's usability for payments.
