I am pretty sure he/she means that this has been talked over and over from time to time and most of us seem to understand that even if that would be possible, listing is not the right move because the costs are more then benefits. There are several points that have been mentioned for and against in this thread.
But isn't registering there actually getting bigger profits in the future because this is a pretty good idea for the long term even though it does require a lot of money but I'm always sure that a good development will definitely require more money and time not a snap.
What makes you believe they won't benefit because the costs outweigh the benefits?
Pros and cons or differences of opinion in this thread will always exist because it is a natural thing where everyone must have their own way of thinking which is considered the most correct and appropriate so that whatever happens if for the sake of progress and development it must be done.
