You don't seem to understand.
Without LP memory, there is significant power usage even with the machine in standby. It's not about keeping your computer in standby for weeks. It's about not losing 25% of your battery life or whatever just because you left your computer in standby for the weekend.
And yes, it is a really big inconvenience to shut it off completely and reboot repeatedly over that weekend as you travel overseas, etc. Anyone who travels should understand this.
As for the 12" MacBook. I don't have that problem with my 2017 model. I can use it lightly on and off over the entire weekend on one charge. If I leave it in standby but don't use it, I don't lose much power at all. Having to boot it up and close it down after each use (which might just be 10 minutes each time) would be incredibly annoying. Often when I'm traveling I don't need to use my laptop heavily, just briefly, but multiple times during the day. I have 16 GB in my MacBook by the way.
No you don't seem to understand. Weekend = 2 days. Ok lets say long weekend = 3 days.
3 days != 1 month. In fact there are 25-28 days in the difference depending on the month.
