barge, with respect,

niche implies nothing about defensibility.

Indeed, focus on the ecology definition from below, and consider a frequent consequence of niche exclusion or collapse. A word frequented in such circumstances is "extinction". The word one uses is business is something like "bankruptcy".

Indeed, if niche implies anything it implies limited, specialised and hence vulnerable.

My statements have been both consistent and within the meaning of the words. You, my friend, are digging a wee bit of a hole.

Regards,

Dig Space.
