I have played just about every kind of map there is to play and prefer no traders. I have played many maps with no towns and only wilderness POIs. I even played a few times with no POIs at all and mentioned a few holes that creates in ones ability to survive (no way to get iron pipes to make a forge to make a pot to cook in, for instance). There are still random loot containers throughout the world but it is very slow going.
You're not wrong, it's a tough world to survive in and tougher still to get out of the stone age. I started doing it as a way to make a "craft everything, loot almost nothing" kind of scenario. TFP does not like this concept for 7DTD so it will be a mod I make at some point after release or at least after the start of beta.
