As it is now, placing fences is a royal pain in the ass. You have to place each section by hand, one by one. Corner, end, and intersection pieces will all have to be cycled through (and crafted!) once they get in.
There’s already a wall tool, though, that does most of what we want to do with fences. We don’t want to stockpile fences, there’s not any particular benefit to having them crafted. It’s kind of silly to expect that a player would keep their carpenter out of commission for eons just to make a nice fence when they could be making more important things like furniture and upgrade tools.
So just use the wall tool to place fences. Corners, ends, and intersections can be handled automatically, a user can just draw a rectangle around their crops or town borders or whatever and they’ll get an instant barrier. Punch in a gate just like you would a door on a house. Builders handle the entire process.
