It's only useless if you assume a perfectly capable attacker. That's not every attacker, though. We're not always up against a nation state actor, in fact, some attackers are quite dilettante. I believe the assumption that if something doesn't defend against the most capable attacker it's useless and we might as well not bother is not helpful.

I know my bike lock can be cut within seconds by someone who is sufficiently skilled and determined. I'm still going to lock my bike.

law enforcement? stolen bags? state sponsored agents? that's the only times you should be worred and it fails horribly at those.

What about employees smart enough to boot a laptop from a thumb drive but not smart enough to disassemble it who just want admin to install some game from a dubious source? What about other scenarios neither you or I can think of right now? The cost of activating bitlocker is so low, I'd do it just in case.

Also, I'd argue the stolen bag scenario usually features dilletante attackers.

I had to think about this and research, but actually bag theft is one of the ways companies are attacked these days.
