You can buy kosher food at 2am in any town which has shops open at 2am (even the pharmacy or the gas station, if it comes to that). How much more so if one avails themselves of all the leniences you accustomed us all to.
Now, if someone wants to buy *meat* and *wine* at 2am, that is a different story. I am, however, not sure where in the Torah it is advised as necessary, or even as healthy, to do so daily or twice a day during the week. Let alone do that regularly in the middle of the night.
Would be interesting if you posted a similar discussion “The cost of having a computer”.
