We would actively try to clean our environment and aggressively implement renewable energy sources in every aspect.
If you want to live long, you need to keep your body fit. Exercise is the cheapest amount of effort you need to keep it healthy.
Yes, there would still be many incurable diseases but society would be doing the best to find a cure.
Torture isn't required to run a pig farm. It happens in a society where profit is the utmost priority instead of rearing and quality. Or maybe developing something like cloning only meat instead of a full organism.
An ideal society would implement something like universal basic income or something similar so that everyone can do whatever they like instead of menial labour. Menial labour can be assigned to autonomous systems or robots.
Nothing lasts forever. You can't do anything about entropy. You can worry for the inevitable demise or live in the moment.
An ideal society would not discriminate anyone on the basis of disability or anyone's misfortunes. There would be extensive therapies, rehabilitations, redresses and in worst case, voluntary euthanasia.

An ideal society would do everything in their power to make it an ideal utopia, so why limit it to some pessimistic depiction even in your imagination.

Life is whatever you perceive it to be. You may have a shitty hand, but it still is yours to play however you want.

True.
Does not make it painless.
Would not help those with those diseases that are (for now) incurable.
If you put a pig in a small pen, prevent it from moving, and slaughter it in the 'ideal' moment, the meat will be cheap. If you allow it to walk on grass, it will burn loads of calories and therefore be much more expensive. If you wait until it dies of old age rather than killing it before it becomes a teenager, the meat will be unaffordable in a society where everyone is equal (for not 3 billion live from a few dollars per day). Lab meat is Sci-fi. If we allow Sci-Fi, we can also allow uploaded conciousness, eliminating all biological suffering, but that's a ideal Sci-fi scenario that no one living today will see.
If nobody cleans the toilets and the sewers, it will become nasty rather quickly. If you pay those that do the dirty work more, you create inequality and envy. Robots are Sci-fi.
The human brain has a agenda of it's own.
There would still be an insane level of suffering required until someone abandons all hope and chooses voluntary euthanasia.

Life is not subjective because suffering is not subjective. If you really believe that life is what you perceive it to be, prove it to yourself by sleeping on a nail-bed starting tomorrow.
