I'll drift into philosophy for a bit here.
Your creativity is only limited by your imagination. No one an internet forum can stop you from doing what you want.
If the question is "why do people give answers that seem to limit your options", well then that is a bit different.
A question was asked. Members answered from their experience and gave advice. Advice can be good/bad or relevant/irrelevant or useful/ridiculous (see this post for example). How you use it is up to you which brings us right back to my first statement.
If you ask if you should use kumquats and arsenic in an IPA you will likely be advised against it for various reasons. No one can stop you but we can pray for your guests.
I ask questions when that little voice inside says things like "you may not want to do that". I often don't know why but if the mental chorus is worried, I've learned to at least consider options.
If I have, what I believe to be, a great idea and others advise against it, I still have the right to try it.
Without people being willing to go beyond the accepted norms, I'd writing this on parchment with ink and feather. We all have the right to dare to be right. Be bold! (but tell me if you put arsenic in your beer before I drink it, please.
)
