[Serious] The Purpose of Pain

[John 6IX Breezy]

I think there is a gap between the argument you hate and your reasons why. Take pain for example:

1. We have pain receptors that are physically distinct from touch receptors; they are activated by different stimuli and take different paths to the brain. Pain itself is constructed in the brain from the information provided by these pain receptors. Analogous to your brain constructing vision from the information provided by your optic nerves and retina. 

2. Pain receptors are extremely important; one could objectively argue that this life would be misery without pain. Pain allows us to avoid harm, it engages important withdrawal reflexes, and it motivates us to rest and protect an injured limb to allow healing (Connors, 2016). There's a reason why being diagnosed with diabetes places you at risk of limb amputations: because nerve sensitive wears out, and risk of injury increases. In conclusion, I disagree with the argument you hate on various fronts as well. But it is clear that in our current state pain exists for our benefit: living without pain is not a blessing.
