Why Governments Cannot Tolerate "Truly Decentralized" Cryptocurrencies
To understand why governments hold this stance, we can examine several core aspects:
1. Preservation of Monetary Sovereignty
Core of State Power: Issuing and controlling currency is a cornerstone of national sovereignty. Governments, through their central banks, control the money supply, interest rates, and inflation, which are crucial tools for implementing macroeconomic policies and stabilizing the economy.
Potential Threat: If a completely decentralized cryptocurrency were widely adopted and operated outside of government control, it would directly challenge the state's monopoly on currency. This would not only weaken the government's ability to regulate the economy but could also lead to the loss of seigniorage (the profit from issuing currency).
2. Risks to Financial Stability
Lack of a Lender of Last Resort: In traditional financial systems, central banks act as the "lender of last resort," providing liquidity support when banks face runs to prevent financial crises. A truly decentralized cryptocurrency system lacks such a central entity to intervene in times of crisis.
Systemic Risk: If an unregulated, highly volatile, or poorly designed decentralized cryptocurrency grows to a significant scale, its collapse could trigger a domino effect, impacting the broader financial markets.
3. Anti-Money Laundering (AML) and Combating the Financing of Terrorism (CFT)
Anonymity and Traceability: A core characteristic of many decentralized cryptocurrencies is their anonymity or pseudonymity, which makes tracing the flow of funds difficult. This poses a significant challenge in combating money laundering, terrorist financing, tax evasion, and other illicit activities.
Compliance Difficulties: Governments require financial institutions to implement KYC (Know Your Customer) and AML measures, but a decentralized system lacks a central entity to enforce these regulations, leaving regulators feeling helpless.
4. Consumer Protection
Lack of Regulatory Safeguards: In traditional finance, banks and investment institutions are strictly regulated to protect consumers from fraud, market manipulation, and systemic risks.
Innovation vs. Risk: While decentralized cryptocurrencies bring innovation, they also come with higher risks, such as smart contract vulnerabilities, protocol design flaws, or market manipulation, and users often have little legal recourse in such situations.
5. Tax Collection
Transparency Challenge: Due to the anonymous and cross-border nature of decentralized cryptocurrencies, it's difficult for governments to effectively track transactions and collect relevant taxes (such as capital gains tax, transaction tax), leading to potential significant tax revenue losses.
Where is the Line of "Tolerance"?
It's important to note that "intolerance" doesn't necessarily mean an outright ban. A more realistic scenario is that governments will seek several ways to "tame" or "regulate" cryptocurrencies, bringing them within a controllable scope:
Regulating Entry Points: Strictly regulating key nodes like centralized exchanges, fiat on-ramps/off-ramps, and custodial service providers, requiring them to comply with KYC/AML regulations.
Issuing Central Bank Digital Currencies (CBDCs): In response to decentralized cryptocurrencies, many countries are actively researching and developing their own digital currencies to maintain control over digital payments and currency issuance.
Regulating Stablecoins: Specifically for stablecoins, many countries (e.g., the United States, EU, UK, Hong Kong, etc.) are introducing specialized regulations that require stablecoin issuers to comply with reserve transparency, regulatory audits, KYC/AML, and other provisions.
Legal Sanctions: Using legal means to crack down on activities that exploit cryptocurrencies for illicit purposes.
Conclusion
Therefore, a truly decentralized cryptocurrency—one that is completely free from external control, has extremely low transparency, and reaches a scale large enough to challenge national financial systems—presents unacceptable potential risks and challenges for sovereign governments. The government's goal will be to integrate cryptocurrencies into its regulatory framework, making them a complement to or a controlled part of the traditional financial system, rather than allowing them to replace its core position.
