Most of us tend to live our lives by clock time not solar time. Again for most of us our waking hours are not distributed equally about clock noon, e.g. up to six hours before clock noon and up to twelve hours after. Daylight is equally divided about solar noon. If we wish to make maximum use of whatever daylight is available it makes no sense at all to align clock noon with solar noon, which is what happens currently in winter. There is an argument for permanently having double summer time all year round but at least a one hour shift forward for the whole year.
I don't recall there being chaos before the EU standardised daylight saving time across the EU and, since they are now abandoning that standardisation, I presume there has been no significant, demonstrable benefit from doing it.
