PA-28 pilot reported that while on final approach reported near miss with another aircraft taking the runway for takeoff.

Narrative

I was on the right base for runway XX at ZZZ; performing touch-and-go and pattern work. Another aircraft was joining me for a couple laps; performing full-stop taxi-back and touch-and-go. I consistently announced my position during each phase of the pattern as I operated in right closed traffic for pattern work at that time.During one of their full-stop taxi-back; I was on the right base; and I spotted them on the taxi way. I announced my position that I turned to the right base at that moment. At a point that I executed a turn to final; Aircraft Y announced over the radio that they were taking the runway for departure on runway XX. To avoid a potential conflict; I immediately performed a 360 on final and announced my intention; allowing them time to depart safely. Going around was not a viable option since it would place me directly above their departure path.At approximately 600 feet AGL; during my turn to final; I believe my aircraft was visible; and I had been making regular announcements over the radio. The decision by Aircraft Y to proceed onto the runway without clear situational awareness posed a significant safety risk. This behavior is dangerous to general aviation as it disregards the critical principle of see-and-avoid.
