I agree. You bring up good points. Allowing them time to distress and adjust to their new environment and providing adequate husbandry is key to the happiness of the snake. Also they don't need us to handle them, but we do as pet owners. I think is good you point out that "eventually it will happen" and you will get bit if you have them long enough. I also think it is good you point out the fact that leaving "fear and hesitation" out of your mindset when dealing with them is great. That way, when the bite happens you don't act in fear but you understand what is going on and don't hurt the snake or yourself more by reacting wrong.
How would you deal with being bitten and care for the bite?
My answer: Clean it out and treat it like any other wound. Get stiches if needed. Try to understand what caused the bite to prevent it from happening again.
If the snake refuses to let go how would you get them to let go?
My answer: I keep some form of alcohol in a sprayer (last resort) near by. Most of the time they let go just as quickly as they bite.
