Doesn't seem disingenuous. Some places still have "character" in a world increasingly turning into the same strip malls and cookie cutter suburbs. In most small to mid size towns in the US, you can't really tell where you're at without reading signs. They all trend towards the same generic look with the same generic stores. Some towns fight this with varying degrees of success. But the Dollar Generals will not be stopped.
One example that springs to mind for me is Pasadena, CA and their trees. They are (or were) very NIMBY about things which would impact their trees. And I can't blame them. It's one of the few areas in the valley with significant shade thanks to their investment and protection of trees. Their roads were planned around mature existing trees instead of cutting them down as is so common. There's no doubt that Pasadena could have more dense housing if they cut down more trees to make room. It also doesn't seem at all disingenuous to feel like that would be a loss for the "character" of the city and a negative for the collective residents due to rising temperatures and loss of shade.

A huge reason for this is arguably NIMBYism. The reason that sort of thing exists is because suburbs very intentionally separate commercial from residential, and will not reconsider as things change. As a result, you end up with putting all the stores on busy roads, and they need parking lots since the people live so far away. All of the homes go in rigidly controlled neighborhoods that are both politically and physically difficult to change. Neighborhoods used to have stores interspersed, old ones, and ones in other countries still do. They don't anymore because we cluster buildings by use in North America, and especially in suburbs.
I'm highlighting the picking and choosing aspect.
Wanna keep everything the same? Sure, argue for that, but that isn't what "character" arguments are about. It is about claiming the things that you like as inside an arbitrary sacred protection line, and the things you don't as outside. Claiming maintaining character if you don't fight every single change is a way of painting over selfish interests in the name of the community. There's nothing wrong with selfish interest, but don't try to hide behind a claim that you are doing it for the greater good, or to preserve something indefinable.
E.g. I could just as easily argue that the "character" of a neighborhood is derived from the affordability and diverse socio-economic backgrounds of residents. Therefore densification, infill, reducing parking for transit lanes and other YIMBY efforts in advancement of those characteristics of the neighborhood are about preserving 'character'.
I'll also point out that your example seems to concern public preservation of nature, not restrictions on private property. There's a stronger argument there since it is a public good. Raising a stink about your neighbor wanting to build an inlaw suite, or - god forbid - a few townhomes, or multifamily housing on their lot is a whole other thing.
