Why is the people are so obsessed with very long term investing and enjoying your money as pensioner.

I was wondering these days after some conversations in different subreddits, why the people is waiting after 65 or 67 years old to enjoy its money.

It doesn´t make any sense, if you start investing in your late 20´s, is normal that you can access to your money at your early 50´s, buy a nice home and have a comfortable live with the money earned and invested in your 30´s. and 40´s I can´t get why wait 30 years just to enjoy your investment, with even high odds of being death before even touch it.
