Will prepaid phones be outlawed in Japan?

This has been captured by a blog and no source has been provided to support the statement. According to this blog, the Japanese government is considering to outlaw prepaid mobile phones based on the argument that too many crimes are being committed.

While DoCoMo would be off pretty well, since they have hardly any prepaid users, companies like Vodafone and Tuka suffer.

Can we conclude that just because a probably small minority commits crimes with phones or through phones, the majority of users are going to suffer?
