Yes, but I think that questions like

1. How come people are able to accumulate so much capital?

2. How come people are able to use the capital to influence life of other people in all ways possible to their liking?

are more interesting and worth asking.

Yes code and capital are both "tools". But you can't just write some code and install cameras at every corner. You need some political influence to do so. And capital buys you this influence.

I don't think you can make this argument. Capital is neither neutral, nor a technology. Currency would at least satisfy one of those two. But capital is a broader concept that is pretty much by definition a form of power, and power's natural tendency is to lead to corruption.
