Sure, no one truly <i>needs</i> anything, but having the right tools can make a huge difference between merely being able to do something, and doing that something <i>well</i>.  I think we all can understand the nerd impulse to really want to get into something, learn as much about it as possible, and do it well.  Having the right tools can easily be the difference between a given hobby being rewarding or frustrating, because you can&#x27;t yield the results you want, or because you don&#x27;t have the right tool to make a really tedious part of the process easier.<p>Some of the more esoteric hobbies I&#x27;ve gotten into have included amateur telescope making, ham radio, long-range precision reloading, and shed construction, all of which are very tool-dependent.  The more and better tools you have, the more capable you are in the hobby, the better your results, and the more satisfying it is.  Sure, some hobbies are more amenable to getting farther along in them with having less stuff, but that doesn&#x27;t help you if you end up interested in something that is tool-dependent.
