My favorite reason for ousting the whole concept of DST is if you conduct international business across time zones.
Consider this scenario, you're an international businessperson who needs to handle a three way conference call between London, Sydney, and New York City.
This isn't an easy thing to do under the best of circumstances, and is made worse when the UK, USA, and Australia don't all agree when DST should be implemented.
The person in Sydney in the spring is 11 hours ahead of London, and New York is 5 hours behind London. However, New York is the first to enter DST, jumping its clocks ahead an hour, making it 4 hours behind London. Two weeks later, London does the same thing, jumping its clocks ahead an hour making New York 5 hours behind again. One week later, Sydney, which is on the opposite side of the world, leaves DST, and moves its clock back an hour.
Good luck trying to get everyone to all agree on a time to schedule that conference call. If you throw Tokyo, Japan into that mix, who doesn't even practice DST, generally speaking, then you got a true Abbot & Costello routine as you feebly try to conduct some business with your business partners across the globe.
Back before our modern, interconnected world, DST might not have mattered so much, but times have changed, especially when you consider that such conference calls are made thousands of times daily in businesses around the world.
This issue only gets worse depending on the region/province/state in that country, because nobody can keep things consistent.
For example, in Arizona, they largely don't practice DST, because good luck not getting ridiculed for suggesting to an Arizonian to get more daylight in the average 107 degree Fahrenheit summers.
Except, the Navajo Nation that lives inside Arizona does recognize DST, except, inside of the Navajo Nation is the Hopi Reservation which doesn't practice DST, except there's a part of the Hopi Reservation that has a part of the Navajo Nation inside of it, which does practice DST, and finally, there's a part of the Hopi Reservation inside of the Navajo Nation which doesn't practice DST.
Meaning, potentially, if you drive through that specific 100 mile stretch in north-eastern Arizona that would necessitate a ridiculous seven clock changes.
Is it even a wonder that they consider getting rid of it, especially when our modern, digital devices can't even keep it straight sometimes?
I personally just don't like unnecessary complications and inefficiency, so thus, I'm for getting rid of DST. Pick one side of the change and call it a day.
