Proposing half-baked ideas may be fun for the proposer but burdens the recipient with explaining why the ideas are unsuitable or mistimed.

“It keeps taking exponentially longer to find the holes on the half-baked idea. Uh, for the person coming up with them, it's fun.”

“I mean, but it's not fun”

“from the receiver, right? You have to do your work now. You spend time telling people why this is not a good idea, why it's not the time you should do it.”
