There's also another story to this.You kinda misinterpret the relatively modern term "aquascaping"
The term "aquascaping" and "nature aquarium" entered vocabulary with the creations of Takashi Amano who elevated tank modelling to a popular-art level. It's based on some disgusting lies. First of all, his creations have nothing to do with "nature". If not for other reasons, then for using CO2. "CO2 injection" and "natural" are incompatible terms.
Amano made his creations not to foster understanding of natural processes but to sell. Similarly, his (posthumous) ADA company sells construction toys to make profit. There's no hint of interest in nature in it. Now, people see it on the Internet, and like the creations. So they follow herd instincts and buy fancy pieces to create the very same. It's almost impossible to see a tank without Dragon Stone and/or Spider Wood.
This fashion is guiding this hobby to consumerist style. People are less interested in the living creatures and care only what they look like. You can see it even here, at UKAPS. This is a site established to promote interest in aquatic plants. And yet, majority of the posts discuss questions like "how do you like my aquascape?"
It's not so much a different story. People use it because keeping plants with CO2 injection is generally easier, and plants grow faster - so it's easier to create "aquascape" - and often develop more attractive colours. Yet you're largely mistaken when you say that these plants can't be kept without CO2; almost all of them can. But it requires something what "aquascaping" does not - patience, precision, diligence, knowledge, accepting the risk of failure, learning on functioning and needs of the plants. These were the features of hobbyists of old times, before consumerist approach with CO2-fuelled aquascaping prevailed.The CO² injection is a different story, that's more about being able to grow bog plants sp. submerged that are not able to grow this way without it.
That said, I admit that the best aquascapes are also based on remarkable skill. Yes, that's true. But it's a different kind of skill aimed at different goals.
