I’m lost in the air travel debate and it sucks. Ignoring the strike and pilots specific concerns, IMHO:

• Emissions of flights are horrendous and will be viewed as barbaric in 30+ years. It needs to stop.
• Denying those of a lower income the opportunity to partake in air travel is also horrendous, and should not be the main mechanism to disrupt the industry.
• There are, in many cases, no alternatives to air travel, so it cannot be abolished.

Smarter regulation is needed, but the finite details will likely never suit a majority of people.

I would argue poo would be the opposite of a higher tier material like gold. Spit maybe?

Would it not be economic suicide to do so?

Bluetooth and the 2.4 GHz ISM band is not electricity and is highly resilient to moderate noise over short distances. Problems are usually caused by hardware related issues.
