Okay. I’ll answer seriously to this. Blockchain can’t store an entire contract (not within reason). Likewise, contracts will never be made public. So at most you’ll get is a pointer to where the contract is held. The contents of the contract can be changed (though you could put a checksum in the chain too), but that still doesn’t address things. Also if you are concerned about “well no one else has a contract” then all that needs to happen is everyone gets a contract, then the chain is inundated with contracts and all you’d have is a pointer and a checksum and you have no idea what’s in the actual contract.

What do you mean by this? I don’t work directly with blockchain, but it appears Eth has a 12MB block limit, which is 10,000 pages of simple text.
A block isn’t a single transaction. It’s way too inefficient to scale that way
A block is a group of transactions
