Others have explained pretty well how to examine your threat model, and what is realistic and what is not.
What I notice though, is that you seem kind of panicked. You're worried about a myriad of different threats. Is there something that has happened in your life that has drastically changed your threat model or did you just read a lot and start worrying?
If it's the second, slow down. Things won't drastically change. Pick one thing (Let's say the recording without your awareness aspect), read up about it, just not on conspiracy websites, understand how privacy controls work, what they can and can't control, how the OS handles these things, etc. Look at what your settings in that regard, look at what you want to change (if anything), and how it affects your day-to-day life. Live with the changes for a while, until you get used to them. Then move to the next topic.
If it's the first, then still look at the different aspects one after the other. You won't be helping anything by panicking.
Yup - I'm for it, in a very specific combination. A universal basic income that is regularly recalculated to ensure that it provides for all basic needs, connected with a flat tax on any income earned through other means and an abolishment of the minimum wage. What it means: taxes become much simpler, the vast majority of people don't need to do them at all. Employers only advertise with net income, so you immediately know what you're getting at the end of the week/month. Since there is no minimum wage (and since one isn't necessary any more due to everyone having their basic needs covered), the economy is more inclusive, since jobs that don't attract as much money but still benefit society like being a musician can be done that much more. Employees have more power since losing their job doesn't mean the threat of losing the ability to afford necessities, meaning they also have a stronger position at the bargaining table.
