The TLD debate is not just about numbers, it's about marketing and aspiration: and no-one with aspirations goes for .biz, .info ... and in many cases, they won't go for local.
Global businesses, whether in China, Germany or any other country, use .com and they will keep using .com in future, as they don't have any choice. Dot net was mentioned as an alternative to .com for those who cannot afford the dot com version of the name, not to reduce the importance of .com.
I don't think anyone claims that .info or .biz can be an alternative to .com. Info has a different purpose and .biz never got any kind of credibility whatsoever.
The comparison is between ccTLDs and .com for obvious reasons, i.e. the introduction of new city and state extensions is in fact expansion of the same idea. I happen to live in the UK and I totally disagree that local businesses use .com's. There are many who do but here we are talking about the general trend.
