It is most certainly not pointless. In the peak of summer where I am, it starts getting light a before 5 am with DST, and sunset just before 9pm. Without DST you’d have morning starting before 4 am and sunset almost 8. Who needs it getting light at 3:30 am? Heck I’d almost double it for where I live, I’d take a 6 am sunrise and a 10 pm sunset if I had the option.
But you can’t really leave it in place all year because then in mid winter, the sunset of just before 8 am would become just before 9 am. People would be at work or school before dawn.
So go to work earlier.
Are you that beholden to a clock that you think forcing everyone to reset their clocks twice a year so you think the sun arises when you want it to makes sense?!
