Oh definitely. Let's not forget the added legal clarity. I don't think we'll see much of a difference short term, but long term this definitely makes for a much more attractive investment.
Yeah, i think that 8% tax was probably never paid that much anyways just like bitcoin tax return forms in the USA

I'd actually argue the opposite of what you just said though - this law is going to have the most effect short term because of the hype generated from it and probably less affect as time passes and people realise governments can't really tax p2p trades in the first place. Just ask people in china, when exchanges were tight with AML laws they just switched to P2P altogether.
But this doesn't mean that i disagree with this law. In fact i love it, and i think it's regulated businesses that are going to benefit the most.
