And even if we were only attention constrained, a project that doesn't work would draw attention away from more promising ideas.

In comparison, plastic is actually mostly just an aesthetic issue.
It's like saying burning oil is mostly bad because of the visual aspect of smog. It's not.

There actually lots of other toxic and non-digestible things floating in the sea, not the least life forms who defend against predators by producing toxins. Therefore it seems unlikely that plastic will be that much worse.
In the same way, you could claim we have no plastics problem, because we don't need plastic. That would be the same logic as saying we don't need oil because we could use solar power.
Maybe in theory it is possible, but it is not a reality yet.
And it is not even proven that it is possible, either. Solar power is not zero impact, either, it may just have a slightly smaller CO2 footprint than oil.
You are hopelessly naive. There is no such thing as a free lunch.
Yes, solar panels exist. That doesn't prove you can fulfill all our energy needs using them. And it doesn't tell you anything about their CO2 footprint.
There is also the tiny problem of energy at night, that has no good solution yet.
