blocks, with DC power being supplied to the people.

DC is worse than AC, with AC there is a momentary time when the
voltage/current goes thru zero and muscles can relax and let
go(sometimes), With DC there is no such chance.

The benefits of DC are that power losses for the same amount of power
received at the far end. are lower. Transformers can't work on DC,
and they are necessary to raise the voltage to high levels so current
levels can be lower and losses lower. So, until transformers became
understood, as Tesla did and Edison didn't, there was that
controversy. Only with the advent of transistors capable of switching
DC and making it into AC was high voltage long-distance transmission
of DC practical.
