Physical books vs Ebooks

I’m have an internal debate about books and I want your opinion on it, the situation is physical book vs ebook. For physical books I’m don’t have much space for them and I’m always moving and it a problem to keep moving them around, I do like to reread my book so I’ll like to keep them. But books are getting expensive and I live in rural Canada so I don’t have easy access to get books. I know there Amazon and Chapters but shipping is also going up and there no guaranteed to get the books. For ebook it solve my space problem, it cheaper, and I get my book right away. My issue is with owning the books and with the ever changing internet that is an important question to ask. I’m thinking of backing up my books to my laptop for a digital library and backup again to an external hard drive but my biggest fear is losing all my book in that digital library. You also need to have a device to access to the digital library so if something happens to my e-reader or laptop I’m out of luck till I get it replace. I am so conflicted on what I should do? If any of you guys are having the same issue as me, I would like to know how you are handling it.
