why wouldn't there be non jedi kicking around? It is a very big galaxy.
Okay, let me clarify. When I first watched the original trilogy, I felt a sense of wonder at the prospect of Luke not only being A NEW HOPE, but possibly THE ONLY HOPE. When we later find out that "there is another", the mystery deepened. But if there's another, and another, and another (you get the picture), to my mind, it reduces the impact of that aspect of Star Wars. Not that I'm trying to put the last of the old/first of the new Jedi on a pedestal, but lots of Force users scurrying around, eluding the Empire indefinitely is a little dull (kind of like how so many people create dark elves in D&D because Drizzt is sort of cool, arguably). Also, it makes Vader seem less competent (again, my opinion, and corresponding only to how I feel about my personal vision of the SW universe) . I envisage a man who has hunted down every Force-user and bent them to his will or broken them on the wheel. Not someone who's head of a crisis management team dealing with some kind of infestation. Then again, if I was to have my way with the prequel trilogy, the Jedi order would be a scant few; secretive and aloof - more akin to the wizards in LotR or the witchers from The Witcher.
Edit: Thought I'd get a semi-colon in there. Gotta love them semi-colons.
In my mind the New Hope wasn't a force user but a child of Skywalker. One or a few force users weren't a major threat to the Empire. Only a child of the chosen one was.
As mentioned there has got to be a regular supply of force users being born since the Jedi didn't procreate and regularly replenish their ranks.
