This should be a given. Any nation-state will want to restrict anonymous currency transactions. It is not in their interest to be in the business of having no information on how currency (power) is transacting.
With that said, they can "want" to end Bitcoin all it wants... I'm sure most nations "wanted" to end Bitcoin at one point or another of Bitcoins life.
It's not about ending something, it's about regulation. Nobody is against Bitcoin itself. They are against unregulated exchangers. Also, it's about a FAIR competition.
If "you" would own a company who is a financial electronic money institutions with a real license, you have a lot of staff, you have to pay a lot of money to cover their salaries, taxes, costs for maintaining the financial license, rent, accounting, auditors and so on...wound't you mind that a company like BTC-e, Bitstamp is doing financial transactions (exactly like your company) and they put all the money they earn in their pocket without paying taxes, without having any rules, without complying with anything?
A small financial licensed company can have expenses of + 30,000 Euro per month. So, each month, firstly, you have to cover the expenses and then to think about you.
You = a person with bills, with a family..with a real life...so you need money as well. Wouldn't you be pissed off because an unfair competitor? YOU WOULD, for sure!
It's VERY hard to make +30.000 Euro monthly from the fees you get from exchanges. Don't look to Coinbase which is sustained by their investors. Coinbase will be bankrupted without them. That company cannot sustain itself by making profit from the fees it gets from exchanges.
