This statement is unsupportable unless you consider every possible use, or produce a mathematical proof that reduces it (in a formal sense) to some clearly superior (for every potential use) alternative.

You suggested a post or two later that it might be useful for criminals. I don't know whether it is or not. If so, that disproves the statement. I submit that you also don't know whether it is useful to for this purpose or another, thus your statement above is incorrect.

A correct statement would be that you can not see a use for Monero. Fair enough.

Of course, many, many, many people have said the same thing about crypto altogether and I'm not sure they are wrong.
