And you’d still have to adjust to local time anyway! Travel three timezones and now noon is at 9 instead of 12. Your alarm to wake up at 6, now needs to be at 3.
Literally sounds a lot worse. Imagine telling your friend in Europe from the USA “ugh, I have to get up at 10 AM for work!” And the european responds with “10am is pretty late!”
Sunrise at 06:00 UTC in one timezone would occur at 03:00 UTC three timezones over, I mean. The relationship between standard time and local, solar noon based time (sunrise, noon, sunset, midnight) is going to have a flexing relationship across different places on Earth. So if you’re travelling or even communicating across timezones, you haven’t fixed anything by using UTC since daily activities (sleep, meals, etc.) are still correlated to when the sun is up or not. Timezones communicates that daily relationship with time pretty effectively without having to do a lot of thought about it all the time.

Right, but I wouldn’t want to keep my daily routine aligned to a different time zone than where I am.

Exactly. So why would I want to adjust my alarm to 3am after travelling 3 time zones? I only care about relating the time between two zones for real-time communication with people in the other zone. And I’m not getting up at 3am for them.
I don’t understand what you’re asking here. I’m saying if you kept UTC in every place on earth, you’d still have to relate those hours to a solar based local time. If you wake up at 6UTC in London and then travel to Moscow, the sun in Moscow would rise 3 hours earlier (guessing, not sure exactly what time time difference is). So if Moscow was also keeping UTC, they would set their alarms for 3UTC to wake up with the sun. If you travel to Moscow, you’d wake up at 3UTC with the sun, which is the equivalent of 3am London time, but is around sunrise locally. This is just how time zones work, so I have no idea where the confusion is.
I mistook your original comment about the alarm clock. I wasn’t reading it as the clocks in all timezones being set to UTC and rather that you wanted to keep your daily routine aligned with the daily solar cycle of the time zone you left.
This is exactly right. People don’t wan to change, even if the new way is demonstrably superior. Look at the adoption of the Metric system in England and the (almost) adoption in the US.
Well, that is neat. When using metric and celsius:
1 kilometer is 1.000 meters.
1 square meter of water weighs exactly 1 tonne. (1.000 kilo also known as a kilokilo)
The vastly superior metric dozen is exactly 10.
Water freezes at exactly 0 degrees.
1 meter of water takes exactly 100 minutes - a metric hour - to completely evaporate when heated to 100 degrees. Doing so requires exactly 1 kilowatt of power.
Your last point is wrong, at least as you have stated it. Evaporation time is based on surface area, and the required power is based on volume, but you expressed the amount of water as a length.
Because we like midnight to happen at night, and noon to happen during the day

Why would you want to get up every day at 6 am from three time zones over?

Ahh, no! I was agreeing with the top comment that using UTC everywhere would cause more problems. Glad we’re on the same page now!

UTC isn’t even demonstrably superior.
For example:
1 bushel is exactly 64 dry pints.
1 dry pint is exactly 107521/92400 liquid pints.
1 liquid pint is exactly 231/8 cubic inches.
We formally defined the inch in terms of the metric system in the 1950s as being precisely 2.54 centimeters.
Thus making the bushel exactly 220244188543/6250000 cubic centimeters.¹
¹ Unless you’re talking about an oat bushel, a barley bushel, a wheat bushel, or a few other exceptions.

Still, metric is way better.
