You didn't write this in all seriousness, did you?
Is it possible to survive without traders at all? Of course you can.
Is it possible to play 70 hours in one world and not complete more than one task? Of course, yes.
The beauty of playing now is that you have a choice.
or or or.
You can find an item, or craft an item, or buy an item, with rare exceptions, but we'll skip that for now.
Everyone will choose an interesting path of development for themselves.
There is no difficulty in adding missing crafting recipes and items to loot.
And if in the future there will be a binding of development to the trader, we will get a game, each survival in which will go on rails.
At this stage, you will only need to find, at this only craft, and at this point only buy. It's terrible.
Trader should remain an alternative, but not a duty.
