Ok, take it that way. Try something different: if the Force is for everyone then why does the director and writer underline in every possible way how powerful Master Skywalker is?
The way I see it, the requisite of the Force being for everyone is that it is an ability that you reach through effort if you want to. If you want the Force to truly be for everyone, then the very concept of “force sensitive” has to be turned down. Which counterdicts TFA as well.
Otherwise it’s a Harry Potter like scenario, an ability not present in most of the people, that can be perfected through training.
