The Why Not Heaven Now Objection to Free Will

If people can exist in heaven and have a meaningfully free life between different good options, then the question arises as to why this can't obtain on earth. I've often heard that the reason suffering or the reason moral evil exists on earth is because it's essentially logically necessary. That seems to undermine the point that in principle free will requires the ability to commit evil. And even if these are two equally good states, the best state of all is to live a life in which we have a choice of whether to be the sort of person who would enjoy doing the life of heaven.
