> Regulation defined as the ability to control transactions.

I'm not sure where would you get this definition. https://en.wikipedia.org/wiki/Regulation

> Regulation may refer to the following:

> A process of the promulgation, monitoring, and enforcement of rules, established by primary and/or delegated legislation.

> A written instrument containing rules having the force of law.

In this context they talk about monitoring and enforcing companies' use of bitcoins within legal system.
