For any system like this to work, there must be losers for there to be winners unless the park is slow enough to give everyone a reasonable wait time.
You say it doesn't negatively impact anyone and then quickly go back to your "everyone has a choice" argument so which is it?
You can't put everyone at the front of that line, right?
Given your feelings about what is fair and what isn't, why wouldn't you be on board with a more exclusive $1,000 lighting lane option?
What's the problem?
I never liked this argument when it came to vacations.
Some people who "play the game" will benefit more than others who don't. That's the way it is.
Some people who pay more will benefit more than others who don't. That's the way it is.
Some people will just get lucky every time with getting a boarding group, others won't. That's the way it is.
This isn't a trial for a new drug to cure a disease, its not waiting for a transplant (although there are requirements for that), it's not getting in line for a food bank....it's a vacation. It's okay to put your wants (not needs, you don't need a vacation!) first.
I've benefited from some of the things Disney has done and others have benefited instead of me at times. (obviously I don't mean by wants, go stand in front of a small child at a parade or something like that...

)
If something works for someone, it's taken away and now what's in it's place isn't as good, of course that person would be annoyed.
And if they want to offer a lightening lane option for people willing to pay $1000, then so be it. Someone would pay it and I wouldn't begrudge them.
