Why don't the whole planet just use UTC+00:00 / Universal Time without time zones?

Idk if it would. As a pilot, Zulu time (gmt 00:00) is used across the board.
The person was rather talking about locally significant understanding of time like "I have to wake up at 4AM for fucks sake.", which has the same meaning anywhere at any time.
But if the same time as 4am now fell on 20:00 people locally would know its super early
Which would make moving or travelling between time zones confusing. Exactly the problem op wishes to solve. Have they considered when the day moves from Monday to Tuesday? Is that at midnight still?
20:00? That's a reasonable time here. Businesses here are usually open from 23:00-10:00.
Thank goodness it's Thursday, though, the weekend is about to start.
Last I checked, kids aren't pilots. You're speaking from a rather advanced concept of worldwide time.
How would you even teach a 5 year old how to tell basic time to begin with?
I imagine not too differently to the way you do now, except the numbers would be different. “Every day the Sun comes up at 4pm and sets 12 hours later. Other places it rises and sets at different times. i think the bigger issue for everyone would be 12am hitting during the day. You can’t just say you’re going to do something on a given Tuesday if every day switches over at 2pm or whatever. You’d probably need some kind of time zone either way to handle it.
Fun personal fact about me: I didn't learn to tell time until I was 9 years old. I was effectively blind until I was 8 when I first got glasses, so I had never actually seen a clock before then.
Don't get me wrong, I already had a concept of time, every time my parents or teachers would say the time numerically, but I simply never actually saw a clock in person until the year after I finally got glasses.
One day when I was 9, my parents left me home alone to briefly go to the local store. Still dumbfounded by my new glasses and how clearly I could see stuff, I started looking at stuff on the walls.
Then I saw the analog clock, just ticking away. I sat there for 5 minutes, just staring at it, counting every single tick of the second hand, and carefully paying attention to the slow movement of the minute hand.
Then I thought to myself 'Well shit, now I get it!'
I more or less figured it out all on my own. But if it was somehow a confusing universal time as OP suggests/asks about, I wouldn't have been able to figure it out on my own and would have still been really confused.
I mean there’d still be clocks and they’d still read the same way, there just wouldn’t be any difference between what they say in different parts of the world.
Zulu time is a pilot?
As a software engineer, I express all time in seconds (plus fractional units as necessary) since The Epoch, which happens to be in UTC, which you might know as "Zulu time." But that's in order to keep a worldwide network interoperable, same as you.
