I do see this as a big benefit.
What are the trade-offs for Monero's inherent opacity?
Do you see it as using one in place of the other or a combination depending on use case? e.g., store of value vs medium of exchange.
Discussion
According to Thorsten Polleit (a Austrian economist) Store of Value is a sub-function of Medium of Exchange.
I would personally agree with that as it makes sense and can also be seen when looking at Bitcoin. It started as a MoE (10k BTC for 2 pizzas and then as the payment method on Darknetmarkets).
So I'd say Monero is very capable of being used as a MoE and a SoV. When you look at the DNMs Monero has taken over. Also if you look at the statistics of CakePay, NanoGPT, ShopinBit, Coincards, OrangeFren, SilentLink and ProxyStore you notice that Monero rivals the combined usage of BTC and LN.
Yeah people HODL their Bitcoin.
Spend that shitcoin monero as much as you can while you still can....
the main tradeoff is that you are trusting more complicated proofs to guarantee supply.
on a transparent ledger its easy to write a program to sum up the UTXO set and check that the circulating supply is what it should be.
this is not possible on Monero since nobody except the sender and receiver of a tx can see the amounts.
that said, the proofs that confirm Monero supply aren't particularly complicated or new.
it just depends on your personal willingness to accept one or the other as "reasonably safe."
