I would look at all religion with high suspicion. What you say may be true, but it certainly doesn’t help our current situation of imprisonment by the demiurge. Following your train of thought, we are supposed to keep coming back to learn different life lessons, which once again paved the way for eternal enslavement. If anything, Buddhists represent only one way of escaping the matrix, and a very inefficient one at that. How many souls have achieved nirvana throughout history? It’s like telling somebody to walk 20 miles instead of drive to work everyday.
