Pirated Stuff and Steem Blockchain - please comment

As i'm quite a while on the blockchain i have started to wonder, whether i could use the blockchain as a storage media ! Not just my pictures that i post through blogging, but music for example that i have from CDs and stuff, or movies. Some may consider their hard-drive isn't large enough to store everything, and may decide to upload movies they have from whatever torrents on the blockchain to have them available for later . Would that be something morally wrong, or what would be the appropriate questions to be addressed ?

And is copyright overrated? As i'm thinking, since all you want to do is storage so that you can see it later and not wanting to sell it or get some sort of incentive, then it shouldn't be alright streaming and downloading and uploading as one wishes? Or what is the fine line inbetween ?
