Not everyone is a concert photographer OP. Some people are nature/landscape who need to hike for miles to take their shot. Others are event photographers who need to be quick on their feet to get to where the action is at.
Also not everyone has a healthy pain-free body. If you’ve injured your neck, back, knees, wrists, or are just older, but you still love photography, you want as light a kit as possible.
Just because you’ve “never” experienced any discomfort, doesn’t mean other people haven’t.
Define “good”? Low key there’s a trend for folks using old school digital point and shoots for a digital retro lo fi vibe. Just go for it!
