You don't need strength.
What you said was ****ing stupid. You need to think about what you are saying.
There is as much light in each day, but the daylight hours shift. There will be more hours of light after any given time, and less before.
But the whole pro-argument assumes people want more light after work. Many don't. Personally, I prefer not to be exposed to the extra heat and I prefer my nightlife and barbecues to be at dusk/night without beginning so late. I also find I can achieve any outdoor exercise without daylight savings in the morning or after work.
Additionally, my schedule doesn't change. I still have dinner at the same time, still have chores at the same time and still need the same amount of sleep. Whatever time I'm outside being active, it's after work/ before dinner where light is abundant without DLS. After dinner, I am more then happy to sit under the patio enjoying a cool evening/night.
If all my boxes are ticked now, why would I want to change that to a system which I find more uncomfortable and outputting?
