Advice on 永住権 please

I’ve been living in Japan for almost 13 years now and am thinking about going back to my home country for a bit, possibly for good. My 永住権 will need to be renewed in a few years and I was mulling over the benefits of doing so.

– I won’t have an address in Japan at that time to be able to renew it, so will I even be able to do so?

– I got PR so I could do freelance work without worrying about visas, but outside that is there really any benefit to having it?

– What happens if I just let it lapse?

I appreciate that these are some pretty stupid questions, haha. But any help/advice would be appreciated.

edit: i know i dont have to “renew” my PR. I was referring to the card expiring. Apologies for any confusion.
