There is no need to influence transactions technically, it's just clarifying existing law - when doing/receiving Bitcoin transactions, you follow the same rules [or else].

No matter if your income is in Euro, Yen, gold, goats, casino chips, redeemable in-game credits, gems, Bitcoin or anything that may ever be invented - that income is taxable.

If you are offering to hold deposits of value for public, or value transfers to third parties - no matter if that is in Euro, Yen, gold, goats, casino chips, redeemable in-game credits, gems, Bitcoin - you need to follow the financial service regulations.

The only way to avoid that is if (while) your "new money" is useless as money, i.e., you can't buy stuff with it.

Of course they can't, but they can regulate its use and acceptance in their country. Eg. more paperwork/licenses required to accept them, a more difficult taxation process, etc.
