It's a little more nuanced than that.
In Russia, they got rid of the DST a few years ago, but then the folks in Moscow (+0300/+0400) were really upset during the winter still living in DST's +0400 from the summer -- they'd never see the sunlight the whole day -- go to work in the dark, come back home in the dark as well. Moscow being quite North (with less sun in the winter) helped exaggerate the issue.
So, after a few years, they've had to change the time in Russia once again -- now to permanent Winter (standard time), with +0300 in Moscow.
What happened in Saratov, which would normally have had +0400/+0500 if sunset/sunrise alone were to determine the timezone? Because having Moscow Time is very convenient, it always used to follow Moscow Time, because there was only a 1h difference from the natural sunlight-based timezone. However, now the difference would be as high as 2h during the summer (+0300 from Moscow instead of +0500 from DST from +0400). So, after a few years of living with permanent +0300 from Moscow, they've finally had enough, and decided to finally abandon Moscow time, and switch to the permanent standard time more appropriate for the geography -- year-round +0400.
There's been similar issues elsewhere in Russia, which, basically, had quite a bit of the timezone map completely re-drawn during all these switchovers of the 2010s when the summer/winter time change has been abandoned.
tl;dr: in the US, we can't simply abandon DST but keep the timezones the same otherwise; we'd probably have to re-draw some parts of the whole map so that each place gets the option to align the permanent time either with the Winter or the Summer. It'll be a bit of a mess. The law in the US only lets the local folk to decide whether or not they want DST (e.g., Arizona has permanent winter time); you cannot decide to keep DST permanently (which is what the parent poster wants, or which is what the folks in Nevada want), or switch to a different timezone easily. I do hope we end up abolishing the time change; but it won't be easy; especially if we simply assume that everyone wants permanent non-DST or DST of their existing timezone.
another tl;dr: basically, in Nevada, a 1h difference from their proper sunset/sunrise timezone is fine to align themselves better with California, but if we abandon DST, then their time will be 2h off in the summer from sunset/sunrise; so, they should be allowed to keep PDT permanently, or, in other words, switch from PST/PDT to a permanent MST like Arizona, which requires US DOT approval.
Of course, because so many steps are involved, it becomes complicated to even say what you actually want.
