Do you see any satellites with hundreds of nuclear warheads? Cloned farm animals? Nuclear-fueled cruise missiles? How about new chemical weapons deployed in battlefield? Or maybe altered embryos implanted in women? These things don't happen because we banned them. There was conscious effort to make it very difficult to achieve. Sure, it will always be possible, but it will require a capital of billions. If you make the government pay the upfront costs then literally anyone and everyone will be able to make their own debilitating, worse-than-death bioweapon, just like they write viruses today or even worse, how they wrote viruses 10-15 years ago. The point is to make it hard or impossible. It's not going to happen anyway. Stop believing the self-fulfilling prophecies of the form "it's going to happen anyway so we need to rush and make it happen now". The assumption is wrong. You don't know what kind of technology will be available in 15-20 years. If you delay it enough, better ways of tackling the problem will become available.
