It isn’t a question of reusable type - you need to have fuel and oxidizer to burn things. A truck can use atmospheric oxygen for the oxidizer; a rocket can’t.

I also imagine that the extra weight of the aluminum pucks would tank your Isp (though I suppose you might be able to make back some tank weight).
