I think 'crabs in a bucket' mentality is not bad when we have limited funds to distribute. Also, if you start abusing this feature your reputation takes a hit.
I just think we should not try to prevent certain behaviors by not providing tools for them. Instead, we should offer all options and let the users decide what is best for Steem. If we artificially limit the options, we put ourselves in the "we-know-better" position.
And there are people what clearly need this option, e.g. @smooth , as expressed here.
