You're taking crazy pills. You're missing out on some seriously nice, and seriously easy, buildings because you don't want to devote 9 squares (at worst) to an event for 6 hours.
At this point, this requirement has been in every major and minor event, and every FA, for the past year. I get that we all have our principled stands, but I'd back off this boycott. Inno clearly isn't listening.
On the other hand, if events just don't interest you, then more power to you. I think that's also a perfectly fine approach (though one that I think makes this game much harder).
Edit: to be clear, this is all tongue-in-cheek. But the fact is that events require you to "waste" city space for buildings you don't ordinarily need to proceed within the timeframe of the event. Whether that's extra tier 1 buildings, 4 random level 3 buildings to upgrade, extra workshops, or 2 nonboosted factories, its all the same, right?
