Just because you might not personally need them, doesn't mean other people don't.  At the end of the day, if you can find a way to build it and it works, it's very difficult for people to stop you.  Which is precisely why no one can shut Bitcoin down (that's a good thing, in case you needed the hint).

Just imagine the number of commercial banks, central banks, law enforcement agencies and governments who wish they could just snap their fingers and make Bitcoin disappear forever.  But they can't.  And yet, here people are saying they want to undermine the very freedoms that make it impossible for those entities to shut us down.  Don't you see how reckless that it?

Building more efficient ways to transact is always preferable versus trying to find ways to stop people transacting.  Because once it's possible to stop people, THEN you'll find out what an "attack" on Bitcoin really looks like.  I sincerely hope no one ever finds a way to prevent people from transacting.  And I wish people understood why that's so unbelievably important. 

Will people please listen to reason and stop being so short-sighted?
