But then we could implement an immortality lottery, to give everyone a shot. That could be the devious slogan: “everyone gets a shot”. Devious because not everyone does, of course.
If you win you get the vaccine and live forever, but your friends and family aren’t included.
Feel free to apply again next time Halley's comet is visible.
You forgot to mention Excel and Word.
But of course a vaccine against aging isn't a ticket to immortality. Death comes in all forms, if you vaccinate against aging, another leading cause of death will come along.
Why not? Surely that would depend on how much it costs to make, maybe it would be cheap as chips?
Oh, I see you completely subscribe to the customer theory of value, where price is dictated by "how much is it worth to the client?"
In that case it would have to be a subscribtion. Or, once you get the shot, the company ownes you. Come to this of it, the two situations are actually the same.
Or we will end up an immortal ruling class cartel...
