It would be much easier to adopt daylight/standard time permanently than to battle all the inertial forces which maintain our cultural structures around times of the day (5pm is when work ends, 12 is when you eat lunch, ...)
I don't know which country you live in but I'm sure young people wouldn't raise an eyebrow if you ate dinner before 8PM.
The general consensus here among young people is that the world is burning so go ahead and eat cereal in your pajamas at 3PM it doesn't really matter.
Having a shared meal schedule across society means it's relatively easy to plan social or otherwise shared events. You certainly don't have to care, but given how large a part of people's lives groups and group activities are, it's hardly surprising such a deviation would lead to jesting at least.
