A hammer won't be able to cut the board.

Not with that attitude it won't. I assure you that, with enough tenacity and/or a large enough hammer, one can absolutely cut a board.

Your analogy is definitely closer though. However, I'd say it's closer to using a flathead screwdriver to chop a mortise. Possible, without too extreme of measures but results are unlikely to be optimal, to hold up well to a heavy load, or offer fine controls.

A simple site, like something that could work on Gopher or Gemini, or simple home page will absolutely do fine though. And, if that's what's required to avoid SEO trash, I'll live.
