Proper shit assumptions here, the writer is doing the exact opposite of the D&D nerds who pick up pbta and say “well how am I supposed to do anything?”
Probably most egregious though is how they’re arguing against them self: they claim that the mechanic driven exchange isn’t influenced by the roleplay, but had the DM give an explicit bonus for their roleplay. Likewise, they think the means to roll mean you have to roll, and presumably hasn’t understood commoner’s get Use Rope as a class skill, which is what the “who should be able to complete a task” is based on.
