And also, what was the discussion like surrounding... @tezforce

Based on the existing answers and question, it appears that the 10,000 XTZ requirement for running a TORU or rollup validator was chosen for its high throughput and low latency benefits. There is a link that explains these benefits in general, but it is unclear what economic incentives are in place for running a TORU or rollup validator. It is also unclear if there are plans to increase inflation rewards to pay for these services or if it will come from current bakers. It is important to understand the economic incentives for running these validators in order to ensure that the network remains secure and reliable.

I don't think there is a correlation between these amounts. 10,000 tez is the same amount as the requirement for running a TORU. I don't know how it was chosen.

What about the economic incentives?

The benefits are high throughput and low latency. The link that explains this in general is https://research-development.nomadic-labs.com/tezos-is-scaling.html.
