It has nothing to do with your point of view. It has EVERYTHING to do with what your iPhone 13 is capable of. And what you want and expect it to do, it can't. I didn't design the new cameras. I don't work for Apple. No one here works for Apple on this user to user only forum.
But I was well aware of the difference between iPhone 13 and 13 Pro cameras and I chose the Pro because its cameras are more advanced than iPhone 13. There should be advantages to paying more for a product. And this is one area the Pro's outperform the standard 13.
I understand you're hoping it's a software thing. I can assure you it's not. iPhone 12, 12 Pro and 12 Pro Max did not have Macro photography abilities. People complained and Apple added Macro to the 13 Pro models this year. It's just not going to come to a standard 13. Sorry.
See this link and compare the features between iPhone 13 and 13 Pro. You'll notice the 13 Pro specifically says Macro Photography, which the 13 does not --> https://www.apple.com/iphone/compare/
