That is of course 100% valid.

Maybe it was not clear, but this is for those situations where that simply is not feasible. Be it from lack of fiat resources to getting stranded in a geopolitical event many will be faced with choices far worse than using an agent.

There is also a lot to be said about learning far more about the system using agents than you'll ever do even if you do it all yourself ;-)

Combining both might be what gains the most reliable and complete knowledge, I kinda ended up in that situation myself
