If you're asking why they were built - because at the time they were 
constructed in the late 18th to mid 19th century, before mechanised road or 
rail transport had developed, waterways of that size could be profitable 
(although sometimes the actual profits did not live up to the promoters' 
expectations). 

If you're asking why they stll exist today - because despite their small size 
and general lack of modernisation, they survived as cargo-carriers for just 
long enough that most of them were still usable when it was first realised 
(initially only by a very few visionaries) that they could have a future as 
leisure boating routes.
