Really? Cryptocurrencies will never be regulated? It's already happening. I'm not making this up to start an argument. Governments are actually starting to implement regulations governing cryptocurrencies.
If you re-read my post, please note where I said the "fiat and retail gateways" would be regulated.
All the examples you cite relate to these. In particular in the name of "limiting anonymity" - again I said they'd try to do that in my post..."unless a mechanism can be found to associate blockchain addresses with individuals"
For example, the article about French regulation cites bitcoin "distributors" - i.e. exchanges and the like.
Another example you cite is the impending imposition of capital gains tax on crypto. That is actually a regulation which applies to fiat - not crypto because your taxable income is measured in dollars euros and you generally pay capital gains on realised gains.
There is also nothing in your examples about a distinction being made between opaque and transparent blockchains.
