I mean, I think it’s a good idea to enable it on a laptop.
I mean if someone steals your laptop they can access all your files without it, and even though 90% of files may be useless there’s always chances to find passwords (often reused, even if encrypted can be decrypted if they aren’t strong), bank details, documents, etc oh and cookies for your browser sessions etc etc. If I were a laptop thief (which I’m not) I’d probably look for those too before formatting everything, that could be extra money.
That’s why I encrypt my laptop’s drive. That way even if it’s stolen the only thing I have to really worry about is not having a laptop anymore.
