The EU's Digital Rulebook: Ambitious in Theory, Fragmented in Practice

What is it about?

The European Union has built the world’s most ambitious "digital constitution"—a comprehensive set of laws (the Digital Markets Act, Digital Services Act, AI Act, Data Act, and DORA) designed to protect fundamental rights online. But does this bold vision work in practice? This chapter introduces a new analytical tool—the Four‑Pillar Framework (4P‑FADGS)—to assess the EU’s digital governance across four dimensions: its rights foundation, legal coherence, institutional design, and ability to adapt to new technologies. Applying the framework to Mistral AI, a European start‑up, we uncover a critical gap: the company triggers strict AI safety rules due to its computing power, yet remains below the thresholds for market‑dominance regulation. It is "too small to be a Gatekeeper, but too smart to be ignored." We conclude that while the EU’s model is normatively strong, its success—and its global influence via the "Brussels Effect"—hinges not on legislative ambition, but on resolving internal fragmentation and building effective enforcement capacity across Member States.

Why is it important?

The EU’s digital regulations have become a global benchmark. Through the "Brussels Effect," countries around the world look to the EU’s rulebook when drafting their own data protection, platform governance, and AI laws. But being a model on paper is not enough. If the EU’s framework turns out to be internally fragmented, difficult to enforce, or disproportionately burdensome for European innovators, its global credibility will fade. Other major powers may pursue divergent paths, and companies might offer degraded services in Europe simply to manage compliance chaos. This makes it essential to move beyond legislative ambition and rigorously assess whether the EU's digital constitution actually works in practice. Our chapter offers precisely that evidence—testing whether Europe can truly deliver a viable democratic alternative for governing the digital future, or whether its model risks becoming a hollow symbol.
