As it says in the description, you still have to meet the attribute requirements to gain the perk. That can be achieved at level 1 by putting 1 points from the starter quest into intellect and finding nerdy glasses. So an early forge in your own base is still a matter of some RNG-luck.
Or yeah. Live in the forge house. I sure love that good old POI. It sure never gets boring XD.
Concrete before day 7 is possible too still, since there's no perk locking crafting cement and c-mix anymore, so again a matter of RNGesus loving you and giving a trader where the mixer works. Or one of those surprise crates that have a rare chance of revealing a working mixer. They're great when they don't reveal a toilet. Or a gas barrel that you accidentally blow up with the next hit. (Totally didn't happen to me, no! )
