Everyone on UTC is really just useful for scheduling stuff internationally and just because of that, telling everyone to change their daily life, so you have it a bit easier, doesn't seem like the right plan. Additionally, timezones aren't really the big issue, it's more the changing of timezones due to DST or similar is what's causing the biggest issue. Getting rid of DST looks like a lot better solution for everyone.
The worst thing about DST is that it breaks the linearity of time, allowing for it to skip back and forth and causing all sorts of problems such as "missing" and "empty" hours.
In my country the train stops for one hour at the spring DST change and just waits for time to pass to account for the "missing" hour and not mess up the schedules by arriving one hour earlier.
