I just really really like the idea of things being permanent.
Your body ages and decays eventually. Less and less physical items are made to last. And even those that are made to last, rarely have "forever" in mind. Software degrades - most of what you had on your 2005 computer is worthless now. Media like photos videos, digitized writing might keep up if someone cares.
Having Bitcoin might maybe be forever. At least hopefully the 24 words + BIP might outlast me.
