> Now, with only my consumer brain, does what they say actually make sense? Do merchants actually want to get rid of the 2-3% transaction fees?

Except that you are now at the mercy of MasterCard/Visa. Sure it might not be a problem now, but things can change quickly. 14 years ago they turned off Wikileaks donations because it violated their "moral standard" while still allowing donations on the Klu Klux Klan home site. They often impose arbitrary rules on adult sites to the point where many small vendors can't keep up, and that is ignoring the 20% fee that they charge for being at high risk of chargebacks.

> who is going to pay the rewards (and loyalty program) modern CC carry?

These loyalty programs are simply offsetting some of the existing costs. If you remove the transaction fees entirely, more money would be saved than leaving them in combination with a rewards program. Maybe that is a hard sell from a Product PoV, but it is not like the rewards are coming from nowhere.

> but isn't this just going back to the age when financial systems weren't developed enough to help merchants acquire and maintain customers ?

Like when the card companies used aggressive tactics and lobbying to prevent vendors from upcharging card payments to offset the costs of transaction fees?

It sounds like you are institutionalized in the sense that you are familiar with all the existing institutions and can't imagine any changes.

edit: Everything I said is more generally in line with cryptocurrencies however. The biggest advantage of stablecoins is for the minter / maintainers. It is a relatively low cost product that can generate a boat load of interest if you can garner enough interest like USDT and USDC have. The only advantage to users is that the prices are (ideally) pegged and less impacted by wild speculation that has been rampant in the cryptocurrency space.

you are absolutely correct about the centralized risks about modern systems, but this is not really something you can use to convince consumers to change their behaviors at scale, besides, cryptos have its own risks.

I am all for changes but they can't take vigors out of markets!

What would convince you as a consumer? If everyday products were 3% cheaper, would that impact you at all? 5% cheaper? At what point do you think people would care? What about cash only businesses? As a consumer would you prefer if you could use your phone instead of pulling out and handling cash?

If adoptions ever takes hold, I think it is unlikely to start with the replacement of payment cards. It is more likely to take hold is specific niches that currently suffer under the MasterCard/Visa duopoly as well as in emerging markets. In the adult industry, I'm sure products being 20% cheaper would sway consumers. Also not to mention the omission of purchases from your credit history which may be judged harshly by others. Low margin businesses could support online and international sales while offering competitive prices. Some markets aren't serviced well by the duopoly. Some consumers value pseudonimity/anonymity in their financial transactions. These can develop into niches where crypto has potential to take hold, and then from there it might expand and compete with the larger markets (and their vigor) if it grows into a competitive product based on fees and usability.

If it ever hits critical mass, vendors will surely either drop card support or strongly encourage cryptocurrency usage. Albeit that is a big "if" that likely comes down to solving a lot of scalability and usability issues right now. There is also a need for regulatory clarity. I think we are a long way away, but I wouldn't write it off simply because I personally find Visa/MasterCard to be convenient in my own life.
