Yep. The Trump administration (and Republican Party in general) has been waging a war on the very notion of experts, expertise, the importance of experience and training, credentials, etc. The only "qualifications" Trump cares about are how willing they are to constantly kiss his ass, flatter him relentlessly, and obey his every whim, no matter how crazy or contradictory. If Hegseth is forced to step down Trump will likely do just what you said - get another Fox News or right-wing celebrity with no actual training or experience for the job to take the post. What will be interesting is seeing how Republican Senators justify and twist themselves into pretzels to vote for his next nominee for the post.
