If electrification can avoid the infrastructure cost and journey time implications of loops, why build them? Avoiding unnecessary spending is not being 'mean'.

Well the traffic is continually growing while the operators insist on sticking with their ridiculous policy of running very frequent but very short (2 or 3-car) trains. If you want to save infrastructure spending the obvious solution would be to operate less frequent but much longer trains, as in the past. Then everyone gets a seat without having to fight for it, station dwell times could be reduced if passengers spread themselves along the length of the platforms, and the effects of late running would be less likely to be compounded and timekeeping improved.
