I was just breaking down how the process worked clearly, for explanation's sake. To do the same with these concerns in a way that will hopefully help:

Bloat is real. Multiple edit transactions can certainly add up. So do the thousands of tiny transfers with memos, or ten times a day auto-posting of 'different' content... to the blockchain, ten edits to an old post and ten similar length new posts look basically the same. This is where we need to be cognizant of how we're using the chain and the outcome of our actions — that's the user end of the scaling!

Since each edit is considered authoring, it's important to note that bandwidth restrictions and resource credits come into play. For example, when bandwidth was strained earlier this year, people would edit and then not be able to post again for the day. They were not realizing that their bandwidth was re-balancing as if they had posted multiple blogs... many people don't understand that each edit is an authored post and then run into trouble with their resource allocation. This does show that the chain has some considerations for this situation.
