And by the logic you guys are espousing, then e-commerces don't accept any currency that isn't the one their government forces them to use either, because they do it through intermediaries like Visa.
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?
