Short answer is no.
The game is about building and maintaining a community. Items have durability too so they need to be replaced when broken.
To be able to function, a village or town needs to be resupplied. You can do this by harvesting ressources and turning them into finished products yourself, or by trading/stealing what you need.
To give you an idea, I can tell you what I usually do when I login on my server:
I'm the blacksmith of my community of six people. We are building a castle. We need flux and flax so I go around the different settlements and usually trade for Iron and Leather that we produce.
That's also the occasion to get to know your neighbors, we allied with another settlement to take down the leader of the main clan on the server and takeover the city.
That means we have to raise an army, craft armors and weapons, train the troops by actually fighting on the training grounds we installed, make battle plans and send spies to try to get some of their people on our side.
There is a lot of stuff happening in this game if you want it to, but you really have to talk to other players and play the social game. If you're not getting involved and you just farm your skills all day watching the green bar you will burn out and quit.
But even without a clan there are other ways to play LiF if you're really dedicated. We have a guy playing by himself who built a trading post / tavern in the center of the island. He also built a road leading from his spot to the main village. He's trading with pretty much everyone on the server so he always find someone to help him or trade what he needs.
