The problem is that the first, last and only point at which goods becomes valuable for the market is at their consumption. Only when something is consumed, i.e. eliminated from the economy, it generates the need for more. Someone has to go and make a new one that can be consumed again. No other economic action adds value to it.
When I produce something, that product (be it good or service, doesn't matter too much) does of course have a cost of its production. It has no value yet, though. Only when I can sell it, it gets a value and I get revenue. If this good is now in turn used to create more goods or services (i.e. if it's an investment rather than consumption), this only adds to the cost burden of whatever it generates, because whoever bought the good/service from me will have to reimburse that investment by means of selling himself. Either that or he will go bankrupt. But I hope we can agree that it's not really a viable business model on a global scale if we drive a good portion of the players in our economy into bankruptcy to keep some other businesses afloat.
Only when someone finally takes a product and removes it from the pool entirely by using it, the value of that good is returned to the market. Note that "use" doesn't necessarily mean "use up". I can consume a house by living in it. You can't live in a house I live in, so if you want a house too, you have to build one. If I use a car, it's mine and not yours, so another one has to be built to sell it to you.
Everything you say contributes to this basic problem, but the underlying issue is simply that goods have to be removed from the market to add value and to drive the economy. As long as they stay in circulation, producing more only devalues them.
