All I am arguing is that except for resolution loss (until it becomes visible) cropping is not inferior to getting it dead-on right when taking the shot. I never claimed it was better.
So if cropping after the fact isn't "better", and always causes some degree of resolution loss (which is going to make the image worse most of the time), why defend it as a preferred method?
I have a lens that goes to 400 mm (35mm equiv.), and I will shoot birds with that lens and no other, even when it means cropping 40 percent. You can claim it's not the right tool for the job, or make any other claim you want, but it is in fact the perfect tool for the job, for all the reasons I've stated.
If you have to crop off an average of 40% of every frame you shoot with that lens, then it is not the
perfect tool for the job. It may the best tool you can afford, or the heaviest lens you can comfortably carry, but it is definitely not ideal. My longest lens is 350mm, and even with a 1.4x teleconverter on a body with a 1.3x crop factor (1D-II), I still find it difficult to shoot birds without needing to crop. It's the best combination of tools I have for that purpose, but it certainly isn't
perfect. There's a big difference.
You'll never understand, and miss a lot of opportunities for that reason
Given what I've seen of your work vs. mine, I'm pretty sure I understand more than you think I do. For example, I understand that if you had used a polarizer when you shot these, you wouldn't be able to see a distracting reflection of the trees and sky behind you in the glass:

It looks like you were wearing a white shirt when you shot the one on the left. Here's a tip: when shooting things with reflective surfaces, wear dark-colored clothing unless you're trying to show up in the reflections. I also understand that if you'd temporarily placed a mirror over the artwork to help you align the camera squarely to the art, you wouldn't have ended up with these perfectly composed and cropped gems:

Most people but their best work on their web site, not their most embarrassing mistakes. If that is true in your case, you have a lot to learn about cropping, composition, and photography in general. Regardless of which is the case, you aren't exactly bolstering your credibility on the subject of cropping and composition here.
You keep making the claim that I am missing opportunities when I shoot. What evidence do you have to support that claim? Have you ever observed me shoot? Have you looked at any of my work, or met any of my clients? No? I didn't think so.
When I'm out shooting personal stuff, I typically pick a subject and then shoot a multiple frames of it, experimenting with various perspectives and compositions. Sometimes I'll only shoot 4-6 frames, but occasionally I'll shoot 20-30, if the lighting is tricky, it's a windy day, or there's some other factor going on that reduces the probability of getting a good capture. My family jokes about me being the only photographer they know who routinely shoots a dozen or more photos of the same thing. But when I go through the images later, I don't have to settle for trying various crops of one loosely-framed capture to see what composition works best. Instead, I can usually just choose the shot of that subject has the best overall composition to begin with.
I'm not missing opportunities; I'm capturing more of them while shooting so I don't have to crop them out of other frames after the fact.
