They also go to mention legalities and crime stats for setting up mines in a fashion that prohibits players from enjoying the mechanic. Grievability isnt that high for this. Checks and balances will persevere.
It's not like they straight up disappear after "days". They just dont work as intended if they break down. Which means you will have to take your NEMO drone and go get them running again. Everything in this game is a money/time sink.
