Sure, in which case they shouldn't be complaining about not having impactful work.
I strongly doubt they'll be on their deathbeds thinking "I regret wasting all that time spent with family and doing things I love; I ought to have made a bigger impact at work instead"
This is a false narrative and not mutually exclusive with doing important work. Most people die suddenly without a community surrounding them, family or otherwise. I'm dubious about the number of people who have great end of life with a loving family surrounding them.
It seems like you're noting a weakness in your original argument as you set up the dichotomy. In reference to aspiring to life on a boat in retirement, you had said:
>> At the end of the day it's just indulgence, not actually using your potential to the fullest. Going through life simply for pleasure is the sure fire way to have no lasting impact.
Not everyone wants that. Some people have had their run "making impact" and want nothing more than to spend time with their loved ones and enjoy their hobbies. I strongly doubt they'll be on their deathbeds thinking "I regret wasting all that time spent with family and doing things I love; I ought to have made a bigger impact at work instead"
