Government has zero power, people always have more power then them.

For example, I recently heard a BItcoin conspiracy theory that stated they are going to destroy Bitcoin from the inside out. Not going to happen, if anything they (for example: Chinese Mining Corporations) will try to take Bitcoin over for themselves. This will inevitably increase the value of Bitcoin so you should buy it anyway before government starts moving in the money and control. If Bitcoin power centralizes government is going to have easier excess to those who control Bitcoin. Though, Bitcoin could potentially lose some freedom because of potential future government involvement and following regulations, it does matter.

Changes in regulation of bitcoin will only lead to mainstream acceptance of the Bitcoin and these changes will come and bring a new and stellar rise to epic value for Bitcoin. Even if you had to pay taxes on Bitcoin in the future, its value would still increase a thousandfold so that it is a net gain regardless.

TLDR; Do not give in to the FUD!
