For the most part, I actually agree with ya HFM...
It's all a very contentious set of circumstances.
The remainder of this post is merely me 'taking the piss' in a quasi light-hearted fashion... It's intent is PURELY to provoke a smirk.
I'd like to take this opportunity to lay claim to the numbers 7 and 823543 (being 7^7).
From this point forward, anyone making use of those numbers shall be considered to have STOLEN them from me and I'd suggest that any use of them (whether for identification purposes or otherwise), is technically in breach of the EULA that I privately posted onto my bathroom wall. (ANYONE can request to come and view this EULA, but I'm not expecting a queue of people).
Anyone wishing to arrange an 'EULA viewing opportunity' may have some difficulty. All my phone numbers contain references to MY digit (7) and I'm actively seeking that all Telco equipment manufacturers around the world strike off this number from their devices. Furthermore, both my street address _AND_ postcode (that's ZIPcode for you yanks) also contain numerous instances of MY '7' so I am afraid 'snail mail' is out. My HAM radio license? Equally affected! I guess you could try 'smoke signals'? (I'd prefer people used GENUINE FTDI smoke, but I will grudgingly accept FAKE smoke too on a 'calm day').
P.S.
I would strongly expect that A210210200 will shortly lay claim to the decimal number 696,055,300,608 (since that's what A210210200 equates to after converting back from hex to decimal). Thank GOODNESS is doesn't include a '7'!!! I'd have been FORCED to sue!
There are countless "illegal" numbers anything in reality can be represented by a number. Everything from your DNA to the Disney's latest movie can be represent by a number of numbers depending on the encoding and base you choose. (Also are you sure you converted my user name properly?, also you failing horribly at copyright law)
And as a good example try making the exact same user name here the exact collision of handles wouldn't be allowed. So locally I do retain limited rights to the handle as do you to yours within the framework of this forum.
Technically speaking cryptographic secrets are also special numbers the only problem is that since they are secret you don't know if someone is using them.
People and governments can successfully prosecute in certain cases of just pure numbers being released and while the number itself isn't property the meaning and use of the number is what is usually being protected.
People own domain names these are also numbers if you could not then everyone could take over any website.
Numbers are merely a medium to represent things you cannot own a number just for the purposes of a number but you can own the meaning/use of a number. Say your DNA can be protected information, a your literary work can be protected, medical data can converted into a number and has countless laws protecting such numbers, and so on.
Math is really neat like that it basically can encode the universe and more. (Nothing in reality owns math because math is probably the closest we will get to the very basics of reality itself)
