In early 2017 at age 25, I bought a C180 as my first airplane with 120 hours total time and an instrument rating. It was the best decision I've made in aviation - it propelled me into aviation more than I could have dreamed. Took me from a PPL to now working in remote alaska as a pilot, doing real (aka for money) off-airport, floats, etc. It was a steep learning curve but no bent metal.
Could another airplane have done the same? Probably, however I gained much respect from having so many hours in C180 early on in my flying career and has opened many doors. A C150 or similar would not have done the same. I sold it when I became a professional pilot because I wanted to lower the expenses. I still have first dibs on buying it back when the current owner sells.
IF you can truly afford one (operating expenses, insurance, etc), why not? However, truly affording one isn't to be taken lightly.
