There really is no reason for it to be longer, more expensive, and more complicated than what exists today in, say, the UK where you can do it all online for about £20 (or is it £50 now?) and complete in a matter of hours.

This is really down to individual countries' red tape and suspicion.

The risk element is also not at all attached to forming a company (hence why it can be so simple and quick), it is with funding and finance. So banks will want to see a business plan but the company registration office does not, or should not, care.
