> It turns out that most recursive functions can be reworked into the tail-call form.
This statement in the beginning is not entirely correct. A more accurate statement would be that all recursive programs that are _iterative_ (if they are loops in disguise), can be rewritten in a tail-call form. That is, there must be a single chain of function calls.
The inherently recursive procedures cannot be converted into a tail-call form.

Insurance fraud. Fleet vehicles and taxis have high insurance requirements and people can get payouts.
I’ve seen videos of people putting their car into reverse to force a rear end collision to make it look like the driver behind is at fault.

Yes, the timing belt or timing chain is inside the engine casing and it can be bad when it or subordinate parts fail. Though a timing belt/chain failure causing a catastrophic event for the engine itself, I don’t think that’s very common. What I’m referring to is called the serpentine belt and is often accompanied by what’s called an accessory or AC belt.

for a mobile app: absolutely not worth while
for a product like a “food supplement”: yes, totally
the model is: right something useful which will get very relevant traffic via google, and be able to convert this traffic immediately to money

What does ownership mean in this context? There’s nothing that the friend can do with those tokens. Transferring them to someone else doesn’t make any sense either.
So how is having a useless token balance on Ethereum any different from having one on a Google Sheet?
