So items 1 and 4 are courses which you need to sign up for and get everything including instruction. That fails to qualify as "on their own". Item 2 is documentation. This is good! But without access to the system to try it out, how self-teachable is it? Item 3 is the one counter point. With a third party emulator though, how comprehensive/accurate is it? Would you hire someone to work on a mainframe who'd never used a real system before? Compare that to e.g. Java. Sure there are plenty of college courses, some even Oracle affiliated, but I can also just download a Java compiler and start plugging away. .NET is there with Visual Studio Express. Oracle cloud, for everything else wrong with Oracle, has a free tier with no time limit. Microcontrollers for embedded development can be had for €20. You can install Linux or a Linux VM on your own computer. Even stuff that falls into the more enterprisey camp like MS SQL or Oracle DB has free personal licenses.

Most Mainframe-Programmer where never near the Hardware anyway...so YES i would do that absolutely (you don't do Hardware near programming in Mainframes, an emulator is perfectly fine), same as a Dev who programs in a VirtualBox, no difference.
