Thanks for clarifying this!  If i understand correctly, your argument
appears to depend on all three of the following assertions:

 a) the chunks of arbitrary data that can be injected in the
    datastructure in question are smaller than some specific size (let's
    call it X bytes).

 b) there is no standard mechanism used for the datastructure in
    question that aggregates multiple pieces of arbitrarily-injected
    data into any larger structure.

 c) there is no toxic data that is X bytes or smaller.

is that right?  I don't know the Bitcoin protocol that well.  What is
the value of X for the Bitcoin blockchain?

Is (a) some sort of general principle that we should try to include in
designs of any append-only globally-distributed datastructures?

how do we ensure that (b) remains the case?  how do we verify that (c)
is true in the jurisdictions that we care about?
