But it is also a rule that the DM does play the player character. Now, the DM is free to infer that a character who chooses to do it anyway (because it is against the rules for the DM to overrule a player character's actions) then they are not a druid. But the rules (as written) do not require a character to be a Druid (member of the druidic religion in good standing) in order to have the abilities of a druid. That is entirely up the DM.The RAW is 'will not'.
Therefore, following RAW a Druid 'will not' do it. They will refuse. That is all.
And again I reiterate: NO ONE is talking about players who are deliberately being awkward. I've never seen it, I doubt anyone else has ever seen it either.
They are talking about how to handle situations that arise through play. E.g. a villain captures the PC druid and locks them into an iron suit. And... what happens?
