One option requires massive cultural change plus invention and creation of new technologies and disrupting uncountable entrenched business models, the other merely requires massive cultural change (although I'd argue comparatively less because its existing deployed in use technology). If its not possible to pull off the simpler one there is little point in trying the harder less likely to succeed option. Its that old advice about minimizing attack surface. Rube Goldberg machines are cool but not good engineering.
