There are no rules and you can do whatever you want.

But businesses are usually closed at certain times because it's not economical to keep them open. There are not enough customers looking to buy a pair of socks at 3AM to justify paying someone to sell socks. Or depending on where you live there are laws protecting workers so they get a bigger pay if they work at night etc. There could be other reasons.

If none of those things apply then it is pointless to apply the same restrictions as if they did apply. That would be like driving a car at the speed of a horse carriage.
