Module 1 raised state-level licensing under Article VI as an abstract question. Module 2 named "regulatory shopping" as one reading of it. This module is where both stop being abstractions: a specific US export-control regime that measurably shaped who builds satellite components, and where.
The Rule: The International Traffic in Arms Regulations control the export of US-origin defense articles and services on the US Munitions List. Many satellite components and technical data have historically fallen under this list, meaning sharing them with a foreign person — including close allies, and including for civil or commercial satellites — required US government authorization first.
Who Benefits, and Why: Large, established aerospace primes with in-house compliance infrastructure can absorb ITAR's cost; smaller US companies and virtually all non-US companies generally can't, and have historically had to design "ITAR-free" alternatives just to sell internationally without the restriction attached. The effect wasn't purely protective, either — international customers wary of ITAR's re-export restrictions had a documented incentive to avoid US-origin components entirely, handing real market share to non-US competitors trying to protect the very industry it targeted.
One Reading
Satellite technology has direct military-relevant applications — imaging, communications, navigation — and controlling its export to prevent it reaching adversaries is a reasonable, sovereign national security choice, not an overreach.
Another Reading
Classifying ordinary commercial satellite components alongside actual weapons imposed compliance costs that pushed international customers toward non-US suppliers entirely — protecting the technology by making sure fewer people wanted to buy it from the US at all.
One piece of context worth having, stated neutrally: in 2013, most commercial communications satellites and their components were moved off the Munitions List and onto the more permissive Commerce Control List, following years of industry arguments citing lost international sales. Whether that reform validates the second reading, or is simply an ordinary policy adjustment, is itself part of the same live debate.
ITAR is one country's answer. Other spacefaring blocs built genuinely different systems.
Dual-Track, Partially Relaxed
ITAR for items still on the Munitions List, the more permissive Commerce Department EAR/CCL for most commercial components since the 2013 reform — a split system rather than one uniform rule.
Member-State Licensing, Shared Framework
Export control is administered at the member-state level under a shared EU dual-use framework — generally regarded as less restrictive than pre-2013 ITAR, a real factor in European satellite manufacturers' international sales during that period.
Centralized State Control
Space technology development is centrally state-directed, and largely self-reliant — partly a direct consequence of decades of restricted access to US-origin components, which pushed indigenous development rather than dependence.
This is Module 1's Article VI question, and Module 2's "regulatory shopping" framing, made concrete: three real systems, three real sets of incentives, and companies making real decisions about where to base operations because of the difference.

Module 4 covers space resource rights — the unresolved question Module 2's Moon Agreement discussion left open.
