I agree with most of the things you said , I don´t think however, that you on are an equal level with him after you already lengthened more than 3 inches. He can do 2 inches more or less easy, whereas you will probably screw your arms/legs ratio and your athletic recovery.
Your environment is a huge factor when it comes to feeling short, 175 is definetely not average for young white europeans. Depending on your location you are still 5-7cm´s below average. There is no discrimnation at this height though, taking a loan to get this done is clearly not worth it.
