You're not convinced... because you understand the component costs and you believe they add up favorably? Or you don't know and don't care?
The answers to your suggestion start with knowing the volume of plastic, time to degrade, degradation byproduct toxicity, and alternative 'recycling' methods and their costs.
There's also clear evidence that the 'current' model and practice for plastic disposal (that you endorse) is NOT safe and effective. Until you can suggest how to fix its demerits, it's unhelpful to blithely suggest we just keep doing it.
