OP is not wrong, but neither are some others.
If trading would be dangerous, then the profits could be well earned. But it is not.
Unfortunately trading atm. is the easiest and fastest, and the least dangerous thing to do.
I am not saying the other activities are dangerous, I am just saying that trading is the least dangerous. You just basically run between A<->B, and you repeat this hours, watching movies and/or browsing some crap.
You are not watching movies while bounty hunting? Nor you do that while you are mining? Nor you do that what ever else you are doing? So I see no sense to protect trading.
If you are not doing something else while trading, I do not know what to say.. You should try it?
edit..
You are actually watching movies while exploring. But exploration income is rather far from Trade income
