maybe they don't make great decorations, but the spiders generally stay in their webs and don't bother me. i once watched one defeat a wasp twice its size. i might feel differently if we had any dangerous spiders around here (just black widows, and they stay in dark hidey holes), but i'm happy to trade a little space for their services.
Some of ours are decorative enough, eg this orb weaver I exchange greetings with most mornings: https://www.pasteboard.co/07o5TWpFLUY8.png
