Not claiming being doused doesn't mean nobody is: If you claim being doused, then the mafia will target somebody else (why waste a kill when the arsonist can do the job for me?), while remaining silent about it opens up the possibility of mafia wasting a kill on you (even better if the arsonist also burns you that night).

My scenario is entirley possible.
And that said, your second argument is actually more convincing. Humans are lazy and dragging a game for 48 hours when the outcome is obvious would be unlikely.
