I see it different, sorry.
I see it like cleaning the dust in the house, although knowing that more will come in.
I see it like cleaning the leaves, although knowing that, especially in the autumn, there will be the same mess again.
Making your surroundings more pleasant or at least bearable (not necessarily/not only for yourself) is not not really futile.
But if you only manage to clean up 2% of the dust and leaves in a certain area, there's really no point in even trying. Just give up on the place, and keep the rest of your house decent. That's why I still report the bounty spammers when they shitpost on the tech boards.
This reminds me of the corporate slogan I often hear thrown around; "The 80/20 rule"
The premise is that resolving 20% of the root causes of an issue will often eliminate 80% of the problems with a specific process. The inverse can also be true; to eliminate the remaining 20% of the problems will require significantly more effort. An assessment of risk, reward, and value of the time and resources required to resolve the remaining 20% of problems will often show the payback is not worth the investment.
