I can understand the reasons why those with a financial stake might want to demarcate their territory, and hey, that's their prerogative. Most of the street photography I see, however, is not subject to their curation; it's on the internet, posted by individuals (myself included) who make their own rules. Trying to apply those rules universally, as many seem to want to do across this vast interweb of ours, seems an absurd enterprise.
Sometimes rules have uses. As I said, I think that too much freedom can be just as stifling of creativity as rules imposed from outside. Setting limits oneself, while difficult (for me, anyway), seems to help strike a balance. Whether it's using a particular piece of equipment, or shooting a specific subject under specific conditions, or whatever else might seem useful, I find I do better with some sort of restriction. I just don't like it when other people seek to impose their restrictions on me, especially arbitrarily.
