I explain a little more detailed. Obtained in advance AS has about zero cost. Real network resources has a solid costs. Resources should be registered at first, like we register a firm before start to do something. We need some lawful resource ability confirmation at first.

Hi Maxim, What stops you from applying for the ASN once the cables are buried several years down the road, and while the build process is ongoing from using a default route instead ?
Nothing, of course.
But it is a little hard to announce your own address space behind a provider if you don't have an AS. And having your upstream originate it just means pain (and usually downtime) whilst they convert you from a non-BGP service to a BGP-enabled one.
I personally have no problem with making it easier to obtain an AS if you intend to multihome at some point in the future (measured in years if necessary - let people who want to do the Right Thing from day one do that). There are plenty of 32 bit AS numbers available, they are not a scarce resource and we as a community should probably not treat them as such.
