that is 540 MB per block. there is one block every 10 minute on average which means 144 blocks per day or 144* 540 MB = ~77.76 GB per day. and you are storing this amount every day
in other words comparing this process with video streaming is wrong on so many levels! first is that you don't store the videos you stream. you just watch temporarily. second you don't verify anything, you just watch a video which will consume little CPU power but a block needs to be verified, you don't just download it. you have to check every byte to see if it is a valid thing or fake. and that takes CPU and RAM and eventually you will find yourself needing only a strong computer to handle a full node and end up with master nodes aka centralization.
