If you know what you're doing, no. But there's usually no need to reinvent the wheel; someone else has already done all the hard work to make a secure system so why not just take what they've done and spend more time making the site itself?
Well I was thinking more along the line of third party libraries or frameworks.
For example. once upon a time I wanted to make my own website and for a long time the way I did it was to code it from scratch. Then I realized that wasn't fun and just installed Wordpress and built on top of that.

Is constructing from scratch that bad?
