This study is a critical review of public intervention and its management of change with digitalization, applied to Spanish tourism services, as ones of the largest case and most required of attention into the European Union. In comparison with other mainstream papers, this heterodox review is based on the combination of Austrian Economics and Neo-Institutional approaches (Cornucopists), with their common theoretical and methodological frameworks. Thus, it is possible to analyze failures and paradoxes in the public intervention, especially with post-COVID recovery policies. The case of the Spanish tourism sector highlights the effect of double bureaucracy, from European institutions and the Spanish Government, affecting its competitiveness and revealing the confirmation of heterodox theorems. Faced with mainstream public intervention guidelines, which usually involve expansive spending and more debt (and New-Malthusian measures), a heterodox mainline solution is offered here, based on the revival of the original sustainability principle, the readjustment effect and the promotion of geek'n'talent education, to facilitate the transition to the Knowledge Economy, where the tourism sector is capable of offering personalized travel experiences due to digitalization.
