Storage size sure if you are running a node, “storage risk” to Bitcoin holders is another concept entirely that doesn’t apply in any way I can think of, and I think that was OP’s intent. A soft fork could be damaging yes, luckily there’s extremely heavy contention for even thoroughly reviewed and low risk changes and that will only become more true with time. Jurisdictional friction, yeah, but again even with maximum friction applied it’s still easier to onboard and transact bitcoin than it is gold.
