Hi Mark,
Sure, feel free to use the positive integers argument. I can’t really claim it as mine because it is well known (to the point where I don’t think anybody knows who made it first). Infinity really is a complex topic; if you want to dive in deeper than is likely safe or sane (e.g. the continuum hypothesis), a set theorist could probably point you in the right direction…
