There is no way you can remember 12 words for years to come without writing them somewhere. Which also means that they could easily be stolen or lost.

true but as i explained, the alternative is still flawed so in my opinion storing the 12 words that is randomly generated is a lot safer than using a brainwallet even if it is susceptible to physical theft.
besides you can mitigate that by using some sort of encryption on it! for instance you could use the "brainwallet" as the password for encrypting the mnemonic phrase and then print the encrypted text instead and remember the password.

That is a fine idea!

What I don't like is using a simple SHA for a password. So even the password protected mnemonics if they fall in the wrong hands could easily be brute-forced.

So here is a thought perhaps we'd both agree on - what about WarpWallet type of encryption on top of the mnemonic phrases?

extending the password with a salt first and then using that for encryption is always a great idea. extending it with a strong key derivation function that is expensive to brute force such as scrypt (which uses a lot of memory) is even a better idea. setting the values for N=2¹⁸ and r=8 is also a good setting for this purpose https://tools.ietf.org/html/rfc7914#section-2
