Yeah no. LHR has one of the highest airport tax, yet still is a leading world hub and annual pax numbers keep going up.

That simply means, from a “prohibitionist” point of view, that the tax is not high enough.

Lol can't wait for 400% beef tax to save the planet /s

plus we can invest that money improving bus services and rail networks, which will help poorer people participate in the economy. If you can't get the bus to work, you probably don't need a plane to Dubai...

What do you mean by improving bus services? Greater West London is the most connected outside of Central, it's TfL policy not to invest in better, cleaner, greener buses not because the money is instead going to LHR expansion.

buses outside of London are (mainly) massively overpriced and horrifically irregular - it's a problem we need to fix right now imo

I agree.

Personally I'm pro expansion but not too concerned if it never happens. However, it will be a great shame if, after all of this effort in the name of environment, these smaller issues I mentioned don't get solved.
