Don't get some ppl on fallout 76?

Love the game love the community love everything about it but just don't understand some people for example I've been shopping around for weapons at people's stores you go to people's stores and they other have absolute junk weapons for sale that you can pick up off a dead scorched for free or one guy just had in his doorway, you had to squeeze past on either side and every time you did you got killed and can't respawn back at his camp and then when you walk back to his Camp he's locking you out locking you in it's absolutely ridiculously annoying all I want to do is buy some weapons and play the game.
