Just because a something is stupid it doesn’t mean every solution to the problem isn’t equally stupid.

For example I’ve not even gotten into the financial cost of expecting everyone to change their documentation, advertisements, etc to reflect an earlier hour.

Sometimes the “worse is better” and in this case the “stupid” solution is actually the better one.

The switching cost is a one-time cost. The benefits are permanent. It hardly matters how much switching will cost, eventually it will be worth it.

Are they going to be permanent though? You’re assuming that people’s routines don’t organically change again over time.

But cost was just one part of my point. The feasibility of getting everyone to change, by their own momentum, was another issue I raised.

Can you give me one good reason why you need to change time at all? Because you have been doing it for hundreds of years isn't a good reason. You can always wake up early if you need to do so. In today's day and age it makes no sense to change the time to suit your needs.

You may have had a valid reason to do so long ago.
