Admit it. The system is just broken here, and there's NO quick patch. :\
I am not sure it is a bad as you make it out to be. Lets substitute the word "Surprised" for Flat Footed...w/o the surprise round rules connotation. In essence the real world equivalent of Flat Footed is being surprised. I would say I do not walk around in a surprised state all day long. Sometimes I detect things before they happen, sometimes I am not paying attention, and sometimes something surprising happens, but for the most part I say I am able to reasonably react to my environment.
I think most people are the same way, thus I would say the rules interpretation of everyone is Flat Footed all the time is bogus.
Traps are an interesting case because is a trap combat? A monster lying in wait is an easy case, player gets a spot check, which more than likely DM rolls in secret, player fails spot check, monster attacks, hits, has a poison similar to symbol of insanity, and player can not use the immediate action, because he is Surprised.
Most players will accept that scenario because they have a chance to avoid the results, (spot check, AC, monster has to hit, saving throw etc). Traps bypass alot of that due to the silly Trapfinding restriction.
I have a condition in my game I term "Surprising". Traps are assumed to have the "Surprising" condition, which basically means the target will be minus dex. The nice thing about this is it is not in the hands of the receipent. Thus on the first round of combat, you are not flat footed, but you might be on the receiving end of of a few "Surprising" attacks if you rolled poorly for initiative.
This lets those with Immediate actions use them w/o the first round exception for being Flat Footed, and does not let someone use Immediate reactions to remove being Flat Footed.
