It leads to statistically significant increases in human death, injury, and financial loss due to stress caused by disruptions to circadian rhythm. The question you should be asking is “why do we still do it despite this, when there is literally no benefit?”
The benefit is more sun. Permanent normal time would give us sunrise at 5 am in summer while permanent offset time would give us sunrise at 9 am in winter. By changing the time twice a year we get 6 am and 8 am.

So, completely unnecessary death and injury directly attributable to the time change is worth that?
No, I’m also in favour of abolishing daylight saving time. But it’s not true that there are no upsides of the current system.
