Yeah, and none of those VMs have any bugs in them.
One point of a filesystem is to have a consistent state that you can recover from after an errant process stomps on memory, or your machine suffers a kernel panic, or your memory becomes so fragmented that you can't even read a 100mb data source, or any other number of issues that can only be resolved by rebooting or reloading.
Once you've committed to non-volatile memory and ditched files, you're tightrope walking without a safety net, at the mercy of the next system level bug. I'd rather know that my data is safe and double-backed up at multiple physical locations, with recoverable history. Files give me that in a well supported, (mostly) system agnostic manner.
