Yes it's possible to make a fire on a plane, but it would be even easier to cause a big fire if there was zero monitoring of bags. As flawed as airport security is, it should generally catch things like somebody trying to get a carry-on bag full of gasoline or extremely large lithium-ion batteries on board.

I take security that catches 50 or even 20% of threats any day over 0 security.
