Because there’s a lot of misinformation in this thread.
All media is physical media. All data is stored on a medium. Data is real and physical. Some data is stored on paper in ink writing, some data is stored as ones and zeroes on a disc drive, but the type of disc drive may vary. Hard drives, USB thumbsticks, SSDs, and so on, are all physical media.
If I destroy a BluRay, or destroy a hard drive, or burn a piece of paper, does the data still physically exist? No. In all cases, destroying the medium in which the data exists destroys the data. Whether it is paper, a disc you put in a drive, or a hard drive.
When something is stored “in the cloud” it’s still on a hard drive somewhere, just not on your hard drive somewhere. You have essentially chosen to store your property on someone else’s private property. Much like a physical storage unit. If the storage unit burns down, everything in it will cease to exist. If the data center where your cloud data is stored burns down without any backups, same issue, the data ceases to exist.
People in this thread specifically only dislike one type of physical media, and it’s a type that has one of the shorter shelf-lifes for long-term data storage.
Also, with hard drives, its often trivial to recover deleted data, which is why companies that deal with secure data often completely shred old hard drives to prevent data being exfiltrated from them after wiping.
