You’re right about the plastic, but just drop the enlightened snark.

As for pottery, forging, casting etc.: completely different processes, different requirements, “vibe” - may not be possible for OP (ever tried operating a forge in a New York city apartment?), might not be aligned with their skills / interests, financial situation etc.

So, what remains is the question: do you believe 3d printing with plastic should be outlawed or at least strongly regulated as a private hobby?
