I'm not saying this sort of setup couldn't look great, but with you 10 gallon in particular the awkward part of it for me is how random and segmented it looks with big plants just stuck behind the background. I love the scape and BG and everything, but the GIANT plants growing out the back (hey, they are healthy at least!) reminds me of that giant plant in Little Shop of Horrors.
It's really not that light IMO. That axie is pretty big and I've seen his huge turds in person.
Now THERE is an idea! I think that has a lot of potential, but you are moving into paludarium or vivarium territory a bit. Why people don't have more interest in either of those types of tank setups is beyond me... I'm setting up my new 41 gallon to be a paludarium.
Justin just uses random house plants you can find at just about anywhere that sells plants... The main one he uses that would work for the application you mentioned is called pothos, and there are a few different species I think, but in general they should all work.
I think even more than your original question Justin of why people don't use this setup is why MFK seems to be plant shy in general? People seem to think plants are overly complicated or something, when they really aren't. Out of everyone who regularly posts, I can only think of maybe a dozen people I know of that run dedicated plant setup tanks with co2 and stuff.
I see guys that can plumb crazy huge filtration systems, build their own stands, talk about water chemistry and stuff for days, but when it comes to keeping a couple plants alive it's like a total mystery to them

I think the answer is that people are a bit hesitant to get involved with something that they don't know a lot about and don't think they really need. Kinda the same reason I haven't put solar panels on my house... You say there's basically cheap efficient filtration available from house plants... There's free energy from the sun (once you got your panels)! Am I going to research and install them? Probably not. It's easier to just pay my power bill, and I imagine that's a bit of the same attitude people have towards this... Just easier to keep doing what they're used to with big water changes and stuff.
Sorry for the derail, I didn't sleep well last night.
