Who would you say does and does not need one? For simplicity’s sake you’re talking about creating a seed via dice rolls, import that seed into something like sparrow (offline) to generate addresses. Could use watch only at that point for convenience? Only use the seed on a signing device when spending? Just asking out of curiosity that you believe this is less accident prone than the threats of malware, error inputing entropy, accidental seed exposure?
