Mayhap. However, we comparing reality vs ostensibility. The reality is, before Surcharging, nobody were screaming enshittification, no business were screaming high CC cost as they all accepted that's the cost of doing business, and most of all, everyone was peaceful.
Words like "Points earning would have gone down anyway" I think are at best, speculation and debatable, never to be proven by history because history would have recorded Surcharging DID happen and now we are in this mess. Remember, even before Responsible Lending kicked in, Australians have enjoyed point earnings and no surcharging for DECADES (at least since I came here in 90s).
Remember how merchants said, "Oh, if you allow surcharging, we won't increase the price of goods and services?". Yeah right. Look at those price of say, dining out. In early 2010s, in Victoria, it is possible to eat out with $7 for lunch. Today, average I think $15-$17. Oh, don't forget, 2% Credit Card Surcharge (Square), and oh, we now want to surcharge you on Saturdays (10%-15%) and Sundays (10%-20%) on top of Public Holiday. Today, they also trying to charge you "Service Fees" aka forced tips despite Australian AWOTE is far more favourable vs USA where workers rely on tips.
It is out of control and good riddance to see this surcharging goes.
