Some of the things he’s advocating seem nonsensical to me.

For example he says it would be a good thing if all railways and hospitals ended up being destroyed.

If all hospitals ended up destroyed what would happen to the people who need treatment for bacterial infections? Or need treatment for heart attacks? Or need dialysis? Or get necrotizing fasciitis and need surgery? Or need cancer treatment?

And if all the railways and factories and such are destroyed how do you manufacture medicine and antibiotics and other devices to save lives?

I understand the things I mentioned just now weren’t around in 1908 when Gandhi wrote that essay but who knows what advancements modern AI could bring that we can’t imagine now?

This is a PDF of that Gandhi book. Under the “A Word of Explanation” you find Gandhi saying he would welcome the natural destruction of hospitals and railways.
