It's total necessary and a great design. Without this then it would be dark until 8:30 in the morning during winter and the other way the Sun would rise at 4:30AM. These are both bad outcomes so we adjust the clocks so optimize these.
Why?
Having the Sun rise at 4:30 is bad because it's just too early to get up and makes for poor sleep. Having the Sun set later in the day is better in this case.
Work when the sun is up, call that 9AM. Wake up at X AM so you can get to work on time. It's all just a label, so long as humans can agree.
But yeah I hear you, some people can be so unreasonable. Nonetheless we should refuse to design our society around unreasonable people.
