Using try blocks for flow control all the time could produce code like this:

try:
  # stuff
  try:
    if userCondition:
      throw NeedToDoSomethingElseException
    try:
      # stuff
    except NeedToDoSomethingElseException:
      # other stuff
  except NeedToDoSomethingElseException:
    # other stuff
except NeedToDoSomethingElseException:
  # other stuff

Performance concerns aside, this is not very elegant. So, sometimes it's perfectly appropriate to use try, but not for everything.
