I think there is a false impression given about simple and complex aircraft perpetuated by flying clubs who want to sell you training.
In the past war 18 year olds were sent off in Spitfires after very few hours so
going from a 172 to a 182 is hardly jumping into a complex demanding aircraft
If you have the money why not ? I had a friend who bought a half share in a Commander 114 retractable before he had got his PPL and moved straight into that on achieving the PPL
So its not about the complexity of the aircraft so much as how much money you have to spare for your hobby.
I see extra power as extra performance and hence extra safety not something to be in awe of
