To my mind, the first point applies to whatever resources are used throughout the future, whether it’s just the earth or some larger part of the universe.
I agree that the number/importance of welfare subjects in the future is a crucial consideration for how much to do longtermist as opposed to other work. But when comparing longtermist interventions—say, splitting a budget between lowering the risk of the world ending and proportionally increasing the fraction of resources devoted to creating happy artificial minds—it would seem to me that the “size of the future” typically multiplies the value of both interventions equally, and so doesn’t matter.
