If you can't create a file in your home directory then either your SD card has gone read only , your system has become corrupt in some way or you have made changes to the pi user or directory permissions.
If everything is working correctly you should have no problem creating a file in the stretch.
I have loaded again for confirmation that if my card is corrupted or system. I loaded stretch again and it was running great until I ran sudo apt-get upgrade.
Then it changed the system read-write permission to read-only and then I cant create the file or open raspi-config or anything. So there is a problem with stretch I think.
