No, that's not it. The reality is that there isn't any particular obstacle
.... that's why nobody has described what the imaginary "obstacles" are.

The rest of your post follows the standard pattern of one personal attack
after another.

You cannot make something true by repeating it over and over in a loud voice.
You cannot invalidate criticisms of your unsupported assertions by launching
continual personal attacks against the parties who make them.

If your opinions reflect reality, and they are not merely the result of
emotional desires or wholesale adoption from people you regard as unquestioned
authority figures, then you'll be able to support your opinions with
explanation and reasoning based on premises that all parties accept. If your
opinions do not reflect reality, you will have no way of supporting them, and
if you hold those opinions very dear, you will become upset and attack anyone
who questions them.

This is fairly fundamental to human behavior and forms a very reliable
pattern. The only way to escape it is to think for yourself, instead of
believing what others say without question, and to base all your opinions and
facts and reasoning, and not on feelings and emotions.
