Because stable currencies do not exist in the world of cryptos? Dai [1], Rai [2], and USDC [3] are some examples that are all stable, and all dramatically different from each other.
Fees are currently as low as $0.03 on Ethereum layer-2 solutions (!= side-chain) [4]. The fees will further fall as the technology improves, and once L1 gets (data-/dank-)sharding and other L2-scaling oriented upgrades.
Fiat transactions often carry fees. If you buy a product online or receive revenue from e-commerce the fees are around 2-5% + 50 cents.
Crypto is probably not going to beat domestic interbank dollar transfers for small amounts, these transactions can be regulated down to zero fees like we see in the EU and UK.

Thank you. It's probably not going to beat domestic interbank dollar transfers for ease of use either. With a CBDC, most consumers will only notice new capabilities and faster money transfers --- at zero cost.
Back to the original point: A CBDC will eliminate any argument for crypto --- except for paranoia.
And about paranoia --- imagine the outcry if government decided to store every transaction you ever did in an immutable public database?
There are reasons to use crypto aside from a domestic interbank dollar transfer: trading a digital asset, registering something on a globally shared ledger, international transfers or transfers to non-bank accounts, anonymous cash-like digital transactions, smart contract functionality, to name a few.
Forcing citizens to use a CBDC is straight out of 1984 playbook.
