I’m sure there’s a perfectly good reason why we haven’t done this yet. Too expensive? Would launching it into the sun cause the smoke (if there is even smoke in space) to find its way back to Earth, therefore polluting the air?
This is an incredibly stupid question.
The frustrating part is that this could be the easiest to solve. Require boats to weigh in and out, and account for everything on board. Minus fuel, plus fish, but those old, broken nets and plastic waste need to return to port to be properly disposed of. Throwing even a soda can overboard should result in significant fines.
How do you weigh a boat precisely enough to detect a soda can missing?
Fair question. You’re not going to catch a soda can, but a boat should be a closed system. The thresholds should be as low as is practically enforceable.
What about fishing boats? They’re coming back with a ton of extra weight in fish.
Containers of fish are extremely easy to weigh.
A lot of ocean trash comes by river from poor countries.
Removed by mod
Also by river from wealthy countries, and has done so for centuries.
The scope of the task of removing it is far bigger than OP can imagine.

Rich countries tend to have better functioning waste collection and disposal services.
These days it is a lot better, but it wasn’t always that way.
It has been that way for many decades.
