See, I don't agree with that.
I think a lot of people who choose the dark side do it because it offers less restrictions. Less rules saying what you can and can't do. I don't think most do it just because it's the "easy" way to power. I think that's just a huge side benefit for many.
The light side, per se, doesn't have many rules, but it is restricting. Yoda says you will know the difference when Luke remains calm, passive. And that's basically what the "central tenet" of the Jedi code "There is no passion..." which Bioware quotes pretty often (even though it originates from very remote canon, a pen and paper rulebook) elaborates. You don't need to obey the Jedi Council to be light side, you must do what is "right", reflecting calmly to find out what that is.
Whether you say that the dark side is more seductive in that it is the quick and easy path (not necessarily to power), or that the light side is too restrictive is basically the same thing backward and forward.
