If I understand this correctly, you are asking for an interest free loan without payback guarantee? DAO would pay 50k and if lucky get 50k back?

This doesn't make any financial sense to me.

I would be happy to vote YES and put the DAO in the position of an investor but then the resulting product should provide returns in that the DAO owns some sort of permanent participation rights.

I.e. if the revenue stream to the DAO continued after the initial 50k had been paid back. I would gladly vote YES. You could offer a permanent 10% once the initial investment will be paid back?
