I'm glad you are having fun struggling to find usefulness in ridiculous levels, but you seem to be one of the only ones who are justifying this junk. (Aside from online noob tourneys) I somehow doubt you are one of the few geniuses who are "seeing the truth." Just play the game as neutral as we can make it, and maybe you'll get better at your character, instead of getting better at situations.
What's the problem with getting better at different situations? Being able to adapt is part of what makes a player good. Part of the problem with SWF is that a lot of stages that aren't immediately understood or largely popular get banned. People talk about Hanenbow and how it's unfair because one of the ledges isn't grabbable or other issues that become irrelevant once people begin to use the stages and figure ways around the issues. SWF is so quick to judge and ban. Anyone remember back in the early Melee days, when people thought Sheik's Ftilt was broken, until people realized that you could DI or CC it?
You argue for "neutral" stages, but there really aren't any truly "neutral" stages. There are always characters that have advantages or disadvantages, however slight they may be, even on "neutral" stages like Battlefield, Smashville, and FD. Look at FD, Falco automatically gains a small advantage there because he can run away and SHDL spam, without the opponent being able to use platforms to aid an approach, alot of other projectile characters gain the same advantage. How different is this from BoE, really? On Smashville, Snake can use the moving platform to set up C4, mine, and grenades as a moveable trap to help his pressure game. On Battlefield, Ganon's >B on the ground lands certain characters on the platforms, where they can easily be tech trapped with aerials, or if they shield they get dropped to the ground for a followup hit. On Yoshi's Story Ganon can't always autocancel Dair because of the uneven terrain, which hurts his game a lot, there are other characters whose autocancels are affecter there too. On Delfino, a lot of characters with precision recoveries have a tough time grabbing the edge since there's no solid wall, and some characters like DK are much easier to edgehog since if there is someone on the edge, they can't just keep pressing against the wall until the invincibility frames wear off, he'll just go right under the stage. There are also walls for infinites and walkoff edges here. Lylat benefits characters like Pikachu because of the low platforms, making platform tech traps possible.
The neutral stages aren't all that neutral really. These are just a few examples off the top of my head, there are a lot of other factors too. My point being that you will never have a truly neutral stage, unless both opponents have to use the same character.
Also, how many times, if any, have their been problems with these stages at tournaments for the reasons mentioned (camping, etc.)? It seems like you're looking at a lot of things in theory, that may not apply all that much in practice. If you have vids or other proof of stages being used to camp without the opponent being able to retaliate, then by all means post them up. But I think we should keep a lot of stages innocent until proven guilty.
