It is useful to have lots of stupid laws. It makes people feel powerless and frustrated. It means the police can always find excuses to persecute you.

The technicalities of the individual laws are not important. It’s the psychological effect of the whole body of laws on a people.

You make a lot of points. To explain all of those things, I would news to make a very long post. i think i will do that when i get time.

Yes block chains predate bitcoin and are very useful. Git uses them. A currency is a perfect use case for a block chain. You need to robustly store balances and transactions so they can’t be tampered with.

I would say it’s insane to have a currency which is not block chain based. Too easy to fiddle your finances.

Proof of work isn’t a necessary part of it. You need to answer the question “how does money get created”. Proof of work is a very robust way to create and allocate new money. Fiat currencies just answer " i nominate one entity who is allowed to create as much money as he likes”. Other answers are possible.

It’s also possible to use a proof of work algorithm which doesn’t consume much energy. The usual proposal is for a “proof of doing work and allocating RAM and storing something on disk”. Bitcoin just chose the most robust and simplest algorithm, which does consume a lot of energy.

In a future currency, the proof of work algorithm could allocate money to people who sequester carbon or plant trees. The thing about inventing a new type of money is that you can do anything. Bitcoin is a great leap of progress for humanity, but has a couple of flaws. Those flawed features can be reinvented, while still keeping all the benefits.

For a start, bitcoin is revolutionary. It solves all the problems with the banking system.

For example, people’s card details get stolen all the time. Bitcoin had solved this by using a new public key for each transaction.

When something is purchased using a credit/debit card, you are effectively using the same public key for every transaction. So what is happening is replay attacks. This type of scam is inevitable because the banking system is insecure by nature. It’s built on a foundation of insecurity.

Bitcoin fixes all that. Bitcoin or similar is necessary for money-based economies to continue to work in the future.

Bitcoin and crypto are more than this. This is just one of the important innovations bitcoin makes.

This is exactly what happens. The highest quality land in a country is used for tillage. The less productive parts are used for grazing. This is how farmers make the most money. They’d be fools to use productive land for grazing and grow crops on poor land.

greenhouse gases and water usage are different issues i didn’t address here.

the usa is one of the “few parts of the world” i was talking about, that it is a bad example of sustainable farming.

yes lots of people cant understand that others can have other ideas about the world. in fact the historical norm for humans is for everyone in the same community to believe the same thing. this time of ideological diversity we live in is anomylous.

of someone says “i believe the earth is flat” most people will not accept that immediately. it’s triggering.

people are triggered by alien ideas. it’s not bad. it’s just being human.

or at a stretch or could be an argument against beef. but the question was about meat generally.

what kind of erosion?

are you thinking of “overgrazing”?

depends on the land. normally livestock are put on land which won’t grow anything else.

that’s true in a few parts of the world. it may not be valid at all, depending where op is from. in general livestock is the most sustainable land use food.

people have lots of different reasons. some don’t like the idea of killing a big animal with feelings and expressiveness. some because of how farms abuse or torture animals in some countries. some think Anibal farming is worse for the environment. some have religious prohibitions. some think it’s bad for your health. some people don’t like the taste or can’t afford it but don’t want people to think they are weird so they tell people they have a principled argument for it.
