Don't yell. Read again. It's not about hours, it's about competency and judgement
If it's not about hours, what makes you think an applicant would suddenly gain massive amounts of competency and judgment-making skills in your extra 20 hours? Even if the applicant was required to do glider and tailwheel and more cross country in those 20 hours, how would that fix the pilots who make bad judgment calls? If more hours before checkride yields more experience and better judgment calls, why do more experienced pilots with hundreds of hours still fly into IMC, still fly into thunderstorms that were obvious and predicted for days, still run out of fuel?
In my humble opinion, competency could be potentially gained with extra flight hours, sure, but the FAA has already established competency standards that don't exactly have planes falling out of the sky all day, every day. Pilots are supposed to continue to hone their skills and become more competent pilots after their checkride, not less competent. As far as judgment skills, those depend far more on personality type and willingness to take risk than they do on number of hours before checkride.
I am a risk averse pilot who had ~70 hours before I got certified. But it wasn't the extra hours that made me risk averse, I was that way from the very beginning. If I had removed the hindrances from my flight training like month-long breaks due to weather, only flying on weekends, and dealing with a six month time frame between my first attempt to schedule my checkride and my first (and only, thankfully) attempt to complete the checkride, I could have probably gotten through in 40 hours. I may not have been as competent as I was at my checkride - after all, I flew most of the flight to commercial standards instead of private, per my DPE - but I would have been perfectly competent in accordance with the proper guidelines and I still would have been just as risk-averse and likely to make good judgment calls then as am I now. My CFI didn't train me to be that way, I wasn't scared into being that way by some in-flight mishap, or anything like that. I walked into flying knowing it was dangerous but that I wanted to do it - so I had to mitigate every possible and reasonable risk that I could so I could enjoy it.
Flying sloppily is a mindset. Taking undue risks is a mindset. Controlling risk is also a mindset. Adding extra skills and hours to the required private pilot curriculum will have close to zero effect on the mindset of the pilot who chooses to take more risks than you are comfortable with taking.
