This is a straw man.
You don't end up with XP triggers like that because no one involved is an automaton trapped following a narrow set of abusable rules. Someone picking triggers such as these would need to justify it in the greater narrative, and should expect the game to make picking those flowers or making it to the ice cream shop a gripping, skin-of-your-teeth adventure, not just s thing you walk into the next room and accomplish.
[EDIT]
On top of that, in this system at least, you're not generating batch XP by pushing a button, each of your triggers can, at most, only trigger once a session. Setting a Goal to "pick some flowers" means that that's what you're asking the GM and the rest of the players to make the entire session about, and you want picking those flowers to be a struggle so that you can claw a single XP out of the session.
