This work coincides with the persistence of the lack problem of consensus on economic methodology between theorists, economists, philosophers and historians of economic thought, as to the anchoring of the work more in economic theory and sometimes very at odds with the facts, events and possible solutions. We support the approach that the theory should be as close as possible to economic reality and try to draw conclusions and "lessons" from the two models which, apparently, nothing compares, one purely theoretical and which has proven itself by its richness in concepts and theoretical notions and its very advanced level of formulation, we cite the General Economic Equilibrium in which Léon Walras describes pure and perfect competition. The second model, or rather a « business model » the Ubers one, mistakenly confused with the GAFAM model and which is intended to be more practical and testifies more than ever to the excessive use of Digital Platforms and their derivatives, the Non-Fungible Tokens, the precariousness of wages, the fragility of the position of workers and the return of the exacerbated prevalence at the beginning of this century of « primitive accumulation of capital ».
