You might as well ask why bother making subroutines, or why bother using OO, since the answers are essentially the same. To give you a real world example, at my work we have built a base class that automates the common pattern of show the form, check for errors, show the errors or process the input, and show a confirmation page. We can add new forms with all of that functionality by filling in a couple of methods (the validation profile and the processing for successful input). We also got a bunch of this for free by using CGI::Application::Plugin::ValidateRM.
Usually, OO and modular code are not about reducing code size. They are about isolating pieces of the code from each other and gaining reuse. Using a module for your web app will help a lot with that.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
