"low-fee" crypto networks are not a comparison because your goal is not to send "low-fee" cryptos, it's to transfer money. Transferring money requires a domestic transfer from your bank account to an exchange, purchasing on an exchange for a 1-2% fee, performing a "low-fee" transfer, selling on an exchange for a 1-2% fee, then performing a domestic transfer to a local bank account. Then adding these taxable events to your income taxes.
Sending money this way is almost certainly slower, more expensive, way more prone to failure and exposes you to tons of counter-party risk. Remember the guy who lost $400,000 trying to send himself money between the US and Canada using Quadriga and got caught without a seat in the game of musical chairs?
A better comparison would be a Wise Multi Currency Account [1]. You get a variety of worldwide bank account numbers. You can ACH into it for free (and SEPA, and EFT, and so on). There is no step two. Anyone in most world jurisdictions can open such an account. Anyone in much of the world can perform a free domestic transfer to send money into it no matter where you are. $0.00. This is what innovation looks like, IMO.
Places payment processors charge you a large fee are almost certainly to cover the risk associated with that transaction - the risk which is not covered when performing a crypto payment. Let alone all the new risks that enter the picture when performing a crypto payment. You're still on the hook for these risks personally, mind you, it's just an unaccounted for externality.
Dig into the business model of these payment processors and you'll quickly learn exactly why they charge what they do.
Unpopular opinion: we have middlemen because they add value.
