The thing about the ebook files is, their usability is dependent on software and hardware that support that file format. Also, a hard drive crash is a lot more likely than a house fire (probably).

There is indeed a big problem with technological obsolescence.
I had fun trying to open some of my dad's old writings from the late 1990s on from a 60mhz Pentium 1. It was very difficult to find a program that would parse them correctly (I believe they were WordStar files then later opened in MS Write but still saved as .doc - but definitely not MS office files despite the file extension).
Ditto with trying to use 16-bit software from the DOS/Win3.11/Win95 era - it simply won't run on a modern OS without emulation or VMs.
IMO a hardcover is a lot more likely to still be good in 30-40 years than any particular file type we have floating around now.
Good quick summary of the problem:

Obsolescence – a key challenge in the digital age
There is a widely held perception that information recorded digitally is secure forever. This idea has been reinforced by marketing messages for products like audio CDs, personal computers and digital cameras. This idea is appealing, but it is completely untrue.
The rapid pace of development in computer hardware, operating systems and application software, coupled with the short effective life of most storage media, means that decades of digital data are at risk or already lost. The long-term accessibility and authenticity of digital records can only be assured through proactive preservation measures.
Digital records are subject to three potential forms of obsolescence:
1 - The physical carrier of the record becomes obsolete. Standard media of the 1980s, such as 8 inch and 5¼ inch floppy disks, are no longer commercially available. Over time, current media such as CDs and DVDs will also become obsolete.
2 - The hardware needed to access the record becomes obsolete. Both the drives needed to read the media and the computers required to operate them have become obsolete in our rapidly changing world. It is almost impossible to obtain working drives for 8 inch and 5¼ inch floppy disks. Most new computers have a usable life of only three to five years and are not fitted with floppy disk drives.
3 - The software needed to access the record becomes obsolete. This includes either the software to read and write the record or the operating system to run the software, or both. For example, during the 1980s WordStar was widely used, but it is now no longer readily available. The fact that WordStar used a closed data format makes continuing accessibility even more problematic.

That said, epub (open standard, fairly popular) and mobi (popular) are probably going to be readable for quite a while, but not forever.
