I see that I was sloppy in my wording!
The Canon and choices and avoidances are not the point of EP but are instrumental. Being instrumental, they are necessary to maximize pleasure (unless one lives a charmed life) with pleasure being the goal. To my understanding if you remove the opportunity to choose, you remove the opportunity to maximize pleasure. Elayne you're correct that this isn't what is spelled out in PD.
Regarding the example of buying a condo: this may reduce the opportunity for choice, but in no way eliminates it. Even after making the purchase there can be continual evaluation as to what might bring the most pleasure or pain: sell it for a profit and buy a more pleasant home, keep it to avoid the pain of moving, remodel it to increase pleasure, sell it because of a more pleasant job opportunity elsewhere, etc etc.
