Annoying? Quite the opposite. Forget the self dissolving property of the web and assume it's there forever. Now you got a material that is extremely light and extremely strong and flexible. Companies are going to pay to collect them. It's gonna be like ambergris, but exclusive to one city. People would flock to collect Spider-Man web. I wouldn't be surprised if Spider-Man web is outlawed by the government and becomes even more valuable.
Parker could simply quit his job as a freelance photographer and sell the formula to his own web shit, because he made them himself and aren't part of his super powers.
This is literally the very first thing he tries to do in the comics before he becomes Spider-Man and it doesn't work because the people he reached out for thought it was too short-lived.
But also, needing to juggle real life responsibilities like having a job is one of the main appeals of Spider-Man as compared to, say, the Avengers.
