That only reduces the problem a bit though, it's not a sustainable solution. We also need to produce plastics that can and will be recycled. Taxation and legislation could be drivers for improvements.
Why not? We lived quite happily with a fraction of the plastic usage 60 years ago. It's possible to continue using plastic for critical use-cases like medicine, or engineering uses like aircraft or automobiles where there are no good substitutes, while phasing out consumer usage.
I'd happily take my refillable shampoo bottle, soy sauce bottle, and milk bottle to be filled at the store.
It's ridiculous how many things are thought of as "disposable" today.
For instance, any hand wash comes with a pretty good and durable dispenser. But rarely do I see refills being sold, except when you specifically search for it online.
And pens, especially ball pens. The outfit is perfectly reusable, while rarely do I see the refill being sold. Instead, it's just 20 ball pens sold in a giant bundle. It's like they want to encourage you to throw away everything.
We need to use recyclable and biodegradable materials or at a minimum, just biodegradable materials (Or relatively bio harmless materials like glass). Even in the best cases, some percentage of material won't get recycled. In many cases, plastic should be replaced by something other than more plastic.
That's ignoring things as basic as: if I need a plastic shampoo bottle... let me refill it? Why am I throwing that away after one use? For that matter why is it plastic instead of stainless steel?
On an individual level, one can reduce their plastic consumption by using things that are not packaged in plastic (eg. powdered laundry detergent, bar soap, powdered shampoo, and so on). It's a bit trickier for many perishable foods in the US (eg. milk, yogurt, frozen foods), since many things are not available in non-plastic containers, but this could be solved by regulation.
