You've got a good point, but when other systems require active work for settings and shippings, LC are faster and need only energy and chests to work at full potential.
If you plan a good energy output in limited space, the logistic center is the most economic and efficient way to move resources once maxed the capacity and energy consumption.
For me have a recipe for it can be a solution for skip bot vulnerability and to have fast resources moving between long discance.
If you use burning mines and inserters, you just need one energy central and you can work only with electricity-less settings.
Gunturrets, burner tecnologies and similar things allow you to have a fully functional sidebase without the vulnerability of electric line efficiency.
If you rely too much on electricity, if critters destroy a single pole the side-base become defenseless and inactive in a second...
