The answer is complex which is why I didn't initially shoot over a short stupid answer.
The software we are running here is FORUM software which programmatically is totally different than social media software.
On social media the focus is on the individual. From the ground up the code is written to look inward on the profile.
On Forum software the code from the ground up is written to focus on community, to look outward.
In a nutshell it's nearly impossible to create the 1 click everyone disappears functionality you might be expecting. It just doesn't work like that. Trying to force it to work like that would break a lot of things and potentially ruin the experience for many.
However we have spent $1,000's to develop individual "blocks" for various parts the site which does indeed create almost the experience you're looking for.
