How is it ridiculous? You can do anything if you put your mind to it. The problem is, people don't want to because we live in a materialistic and greedy society where people expect things straight away.
Spend a few years saving and making sacrifices here and there and before enough know it you will have a deposit ready. Allowing you to own your own home and you can spend many years doing the things you want to do.
Unless you are rich, have rich parents, or have been left with a decent inheritance then there's no other way.
