In order to define boundedness, you require some kind of ambient space in which to embed your set. If your ambient space is a nonmetrizable infinite topological space, you may be right, depending on the topology. Cantor, however, worked with densely ordered metrizable spaces. These spaces have a measure, called the generalized Lebesgue measure. With regard to this measure, the size of a finite number of elements is 0. Hence adding a finite number of elements to ANY subset of a "cantorian" space does not change its "size" (i.e. it's measure).
