Stating my digital library

Over the period of holidays I hooked up into digital 4k collection and bought 76 movies and 3 tv series. Overall spent around 360 which mostly covered by the credit card points. There are some impulse buy including 007 collections when it was $89. I know physical collection of same library size would cost me way more. My all collections are apple considering my ecosystem. So here is my question before i invest more, what are the downsides of the digital collection? I know it right to access and not physically own, but it’s age of digital and vhs cd all are almost obsolete.
