Peter Thiel's relocation to Buenos Aires has drawn protests and political scrutiny after Argentina's government, led by Javier Milei, introduced sweeping regulatory changes shortly after the billionaire moved his family there in April. Critics, including deputy Juan Marino, argue the proposed laws would entrench the power of US tech billionaires in Argentina, calling the package "technofascist" and noting that Thiel, Milei and an intelligence-linked official all declined to answer questions at a congressional hearing on the matter.

Among the measures debated is the "super RIGI", which would offer foreign investors, including AI datacentre operators, minimal tax rates and 30-year protection from regulatory change, while a separate decree would require government departments to share extensive citizen data with state intelligence services, raising concerns about undisclosed contracts with Thiel's company Palantir. A land-ownership deregulation bill, which failed, was seen as a potential path towards autonomous "startup cities" that Thiel has previously championed. Although no direct evidence links Thiel to drafting the laws, his closed-door meetings with Milei and senior officials, alongside Milei's own advocacy for AI-run "non-human corporations", have fuelled suspicion that Argentina is being used as a testing ground for techno-libertarian ideas.
