You do understand that "infinite data on a disk" doesn't exist, yes? And as the chain goes on longer, more space is going to be needed, and centralization of the miners will continue to increase, yes?

The former may or may not happen depending on how widely it is used, certainly not everyone will have the full blockchain on their devices due to storage requirements. The latter is a social issue not a technical one.

One can definitely make an argument that Bitcoin will lose its social relevance in 100 years. Or 500 years. Or 1000 years. Do you see where i'm going with this?

Most of the OSes currently in use might not be relevant in a century. Most of HDDs or SSDs in use currently won't be around in a century, unless they're a part of an abstracted and clustered storage pool, which would take constant effort to maintain. Even short of the technical concerns, there is still need for social relevance - if and when it eventually ceases to be relevant, no one will care much about maintaining copies of the full blockchain, except for maybe in some museum archive.

Using a globally distributed store like that is a good idea, but it's definitely not foolproof. One of the better ways, perhaps, but maybe there are even better ones, that you or a foundation in your name controls, with properly sourced funding and preservation of data being its sole and primary concern.
