OK. Then, as long as the expected profit from building a factory is higher than zero, I would not lend the money at zero interest rate.
Maybe to make a point more clear. As long as there is some opportunity for me to invest in a project with positive expected profits (whatever it is - building a factory, running a restaurant...) I would not lend the money at zero interest rate. And not just that. If I am really good at what I do, I would probably need some extra cash so I would be willing to pay someone to lend me that cash. As long as people are reasonably risk-averse, they will prefer giving money to me and risking it than giving it to someone else for free with no risk. So, if you assume that there is only one way of lending the money risk-free, while other ways are risky, there will always be someone who is willing to take that risk and be compensated for it. But then, it looks like a real world... That is why I assumed we live in a risk-free world. I guess the short answer to the question "Why is a dollar today worth more than a dollar tomorrow?" is "Because there are some people who know how to take $1 today, transform it in $2 tomorrow and pay up to $1 for that."
