If there are easy alternatives with the same outcomes, hard things absolutely should not be done (unless you're practicing for an emergency situation where the easy thing is not available.)
Even in a utilitarian framework, there is more to consider besides outcomes, such as costs.
Examples of costs could be be the reoccurring monetary cost for the rest of your life, and being dependent on the supply of medicine to maintain your health.
Additionally, there are personal advantages to being an individual that is capable of doing and regularly practices "hard things".
