Complex economies rarely have "super simple solutions" without pitfalls, but I get where you're going with this.
The hardest part with implementing any solutions like this is that they require breaking down the existing systems. This will always be aggressively fought by the rich and powerful who benefit from the status quo, usually by flooding the media with straw-man misrepresentations of the solution to turn the public against it.
Your solution would likely require the government seizing large plots of land from private citizens/companies. This could easily be re-framed as a "The government is stealing your land" bill.
