The paper forms a rejoinder to the paper by David Weaver ('Organic, incremental and induced paths to sustainable mass tourism convergence'). It fully agrees with David Weaver that a sustainable development of tourism should focus on sustainable mass tourism development and not, as is currently the case, so much on niche products labelled 'sustainable'. However, it critiques Weaver's operationalization of sustainability, his assumption that sustainable mass tourism (SMT) will be the 'emergent norm' due to external factors, and his destination development theory showing different paths that, however, all end in SMT. Finally it is shown that the path development idea might be at odds with systems thinking.
