No shame in increasing your carry weight. This game is meant to be played the way you wish. You can role play it for thousands of hours or cut through it in a few days and be done. Fast travel or no? Reload after a mistake or no? People put a variety of limitations on themselves because as was mentioned before some things are very far from realistic to start anyway. As long as it's fun for you and doesn't ruin it then awesome! I ruined Skyrim for myself. Bought it on 360 and played for about 100 hours. Decided I wanted to get back on the PC so got a copy there. 30 or so hours in I increased my carry weight. Then I changed something else. It trivialized the game for me and I lsot interest within a few days where I had been totally ingrossed in the game.
I'll confess my Fallout 4 sins here. I have a ton of mods that are quality of life related. Graphics, weapon drop for better first person visibility, much darker nights, sixy underoos for my Lone Lady. But the only thing I've done that's... cheating.... I installed a particular mod to change the rate of Fusion Cores consumption. And.... I have it set to 0%. I was using power armor 100% of the time and collecting as much of it as I could. I decided that I didn't want to defeat the mechanic and the struggles of finding them, running out and all. No. Instead my goal was to play a character that was always in power armor.
For the last 40 hours or so since I got ballistic weave and decided nothing could kill me I retired power armor and now simply collect and customize it, never use it. So in the end I made the game enjoyable for the specific style I desired and eventually invalidated the cheat. 204 hours as of last night and I'm excited to complete the remainder of the game, start a totally different type of character and await DLC.
I pray that Atom will forgive me for my sins.
