I do not know why people want to fear Bitcoin regulation? We did not expect that governments will sit on their hands and allow Bitcoin and other Crypto currencies to go unregulated? How would we know how to submit our taxes, if we did not know how the governments defined the technology?
Let's just be glad that they acknowledge the technology and that they are taking the effort to regulate it.
I can now pay my taxes and go on with my life, without worrying about them. ^smile^
There are probably two reasons for this, first people are afraid of change, people that have cryptocurrencies are so afraid of regulation as those that prefer to fiat system and fear cryptocurrencies, another reason is that even if what you say is very logical and it was impossible for governments to stay out of cryptocurrencies the truth is that people have gotten to used to not pay their taxes and it seems they do not want to do it.
