Earlier quoted context omitted.
The logical response to "it's all just computation" is "put your hand in this box, I have a 'computation' I'd like to run." Sometimes logic isn't enough to get out of the trap that logic got you into in the first place.
If you can recompute my hand back after that, i'd be happy to put it in whatever box you want, the thing that is valuable to me is the time i still have to live, not the absence of all pain. If i had lots of time, and sufficiently advanced technology, i'd happily play realistic games where i had to go through torture by medieval inquisition, or other interesting ways of dying. And i'll be happy to go through any amou…
I'd bet good money that such an experience would very quickly show you why having "computational resources" taken by someone else is so vigorously avoided by most creatures.
The parent comment's thought experiment of "if all pain is just computation, let me 'compute' your hand" neatly refutes the practicality of your stance. Sure, pain is mediated by the same physicochemical processes that govern every other aspect of our bodies. Tell that to someone suffering oncogenic bone pain, or a second-degree burn, or the pain of losing a life partner of 70 years.
You claim that you value the time you still have to live, and not the absence of all pain. What about your quality of life, whatever that means to you? Have you ever had, e.g., an infected tooth, been hit hard in the groin, or even badly sunburnt? What value, if any, do you place on the privilege of not having to "compute" those sensations?
Moving beyond physical pain, what's the longest you've ever stayed awake? Acute sleep deprivation causes no permanent damage and no physical pain, but real-world evidence confirms that at some point, subject to nonstop sleep deprivation, you would do anything that you thought could end the experience. I would. Anyone would. Some people would of course last longer than others, but everybody cracks, computer-simulated or not.

I don't mean to dismiss your generosity or confidence in your ability to accept pain, but it's very easy to express this sentiment from the comfort of a relatively healthy body. It's true that looming certain death changes a person's attitude toward pain, but I would suggest for your own subjective (not logical, but subjective) wellbeing that you tighten up your "any amount of suffering" threshold.
