>>Who said anything about ethics? Corporations accepting Bitcoin is evidence of its usefulness.

I don't buy that either. The only thing it is an evidence of is that said corporations want to attract customers of a specific demographic. Overstock.com CEO himself is a libertarian, for example. If it wasn't for him I strongly doubt they would have implemented Bitcoin payments on their site.

I mean, if Bitcoin is so useful, why have sites that have implemented it have done a miniscule if not virtually negligible amount of sales through it?
