It creates a divide between people that are looking for a solution to a problem, and people that disregard the problem completely. If you just ignore the actual problem and cynically call it a front for something else, you are just going to be ignored in the actual conversation. The problem is real and it needs a solution, suggest something better or be forced to stay out of the conversation.
For example, if there's a lot of car accidents, and we suggest a speed limit, you might say that it's actually a way for cops and cities to control the population, and make everything slow, and increase city income by charging fines. But the problem still exists despite your cynicism, unless you suggest another solution for the problem, you won't be able to keep your precious speed freedom. Because of course reducing car fatalities is more important than the freedom to go super fast, that's not really under discussion.
