Earlier also, I had a long debate with fellow forum members on similar topic. It's true that blockchain ledger is open for public and every information is traceable there. But that doesn't really matter because even if the information is available, the information owner is not known! So even if we see someone sending millions of dollars using bitcoin, we don't know who is doing that! So the information matters least unless you can link it to an owner!
I am not bitcoin puritan but I really want to see a clean bitcoin network rather than being synonymous to illegal things! Just check the number of financial frauds happened in last 3 years and see how many are connected to bitcoin. Not a good picture, really!
So for me, this privacy feature of bitcoin is really taking us off-track than bringing us on-track where we can see organic growth among the legal merchants and users. Really sad to see!
But let's be real, the fact that bitcoin gives the possibility of anonymity is a net positive. You may not like some of the implications of it, but I personally prefer to have my savings stored far from my govt's reach. Simple as that, just think how much money is taken from you in taxes at any given month and is just normal to you, well, it's not okay. And privacy is a good way to combat it. Yes, I know taxes do have good uses, but see the current US political stage and you can quickly realize how I don't want my hard earned money just mindlessly spent against my countries' own interests. But maybe that's just me.
