Because all ballparks don't have the same dimensions and that can drastically alter "production". Of course, in some places you need to score more runs to win and in others less runs because the overall scoring environment varies.
OPS+ attempts to equalize OPS for all of the parks that a player spends time in. Playing in the West (in either league) that isn't also Colorado or Texas, you are going to spend a lot of time playing in very large ballparks that are very tough on hitters production.
You don't have to adjust for those things if you don't want to. I do though because I think it matters.
