Stupid it may be, but there are a lot of places in the world that already do that and are effectively already going permanent DST. In fact, some of these places then also do DST again, making double DST. Don't believe me? Well, let's look at a time zone map:
Time zone map
Places that do DST
Consider the US state of Alaska. It is nominally in time zones -10 and -11 (check the water north and south of the state). But for some reason, the whole state is in -9. And for some reason, despite their high latitude, they also do DST. I guess they have so much, or so little, sun that it doesn't really matter if their clocks align to it, but then why change twice a year?
But a sparsely populated place not very interesting? Then consider China. Despite being 4 time zones wide, the whole country is in a single time zone (+8). The western border of China is in effectively triple permanent DST. Must be annoying to have solar noon at 3 in the afternoon. At least they don't do DST, through, and a lot of China's population is on its eastern side, which is in the right time zone for its longitude.
But maybe an authoritarian dictatorship isn't a great example. Then turn your eyes to France and Spain. They are effectively south of the UK and effectively in the GMT (+0) time zone entirely. But for some reason, they choose to be in the +1 timezone, giving them permanent DST. Then they also do DST in the summer, making it effectively double DST.
Basically, a lot of time zones "drift" to the west. There are probably a lot of reasons for this, some reasonable, some perhaps less so (the cynical part of me thinks it is older leaders trying to get younger people to wake up earlier and stop sleeping in, though it is actually hard to assign that much forethought to country leaders).
Interestingly, if you look at the DST map linked above, it is clearly just a European and US concept. Not to get too political, but I expected the non-thinking, white-things-are-bad, extreme TDS sufferers to loudly call for an end to DST now that Trump supported it so strongly, but so far that doesn't seem to have happened.
