Hmm, that is helpful. Though I am talking about Day 1 stuff, I don't have any archers or helpers at all. I also don't have the option to craft most of these items I think. But I do have the wooden spikes, I guess I will try to make those and see if the enemies will kill themselves on it? My current base was half wood half stone and they just hit the walls until it broke.
I mean, it's so cheap to erect this basic defense at the start and it can be repaired with minimal costs. So just AppalingBlue said, you can just add spikes and they will die over time. This is what I did when I started playing for the first few days of trying this game out. They eventually die before the wall breaks, especially if your main base is at the beach. Using stone walls is also cheap and holds out longer for the small raids.
Once you can relocate your base, yeah, building the main base in the cave and having a NPC holding a decoy charm will stop all future raids at that point.

Personally, for me, I just went with no defence and letting the male character deal with random scouts while I speed run in getting the end game workbenches to accelerate personnel equipment and setting the terms of the raid. I managed to do this under 10 to 15 in-game days.
However, if the alternative way is to just speed run and get the plant workbench and build that statue to minus raid numbers to the negative, and there will be no raids, only scouts and their level is based on your location of your base.
