Aside from all the semantics about confusing regulations relating to practice IAPs... let me invite you to consider the reason we exercise such evolutions... to remain current and to maintain good practice.
IMHO the regulations are written from a common-sense perspective... to achieve the objective of a practice approach it may be beneficial to have the oversight of a qualified instructor. The regulations are not about the pilot who wishes to grab an opportunity for a bit of practice... but about training and currency.
Finally, the posts about the level of separation/information you receive is worrying... it has nothing to do with whether you are practise or not... in Class G airspace it depends on what type of service you ask for (FIS/RIS/RAS)!!!
