Don't confuse the amount of time that it takes to completely degrade

Irrelevent. The material doesn't wait 500 years then suddenly
decompose completely. It decomposes over the entire period
releasing toxins the entire time.

Then ban those dangerous styrofoam beverage cups!

Surely disposing of them properly (e.g. recycling or
landfill[*]) is sufficient.

The point was that if they are toxic, they emit dangerous
substances, then why are we drinking hot beverages from them?

For reasons similar to the fact that you're ok drinking wine from
lead crystal but you shouldn't store it in lead crystal. Exposure
over time.

Easy enough to find FDA approval for polystyrene contacting food:

Polystyrene is a poor choice as a food container, e.g. a wine bottle
because of poor oxygen permeability:

I just had to toss a 10 year old bottle of wine with a synthetic cork.
It was turning to vinegar. Never seen this with a natural cork although
they do breathe.
