1. you need loan to expand the production capacity, but now it is over production in major developed countries
If this were true, it would still have nothing to do with Bitcoin, and loans should cease today.
It is true and loans are ceasing now, FED printed 4x more dollar since 2008 but most of them went back into their account as reserve, because most of these money can not be loaned out due to extremely weak investment demand. Please give me an example of some investments that can bring you very high return that you need large amount of loan? (except bitcoin)
To create a real example of this, let's say someone came up to you in 2004 with this thing called an "iPhone" (and let's say Bitcoin was the currency). He says he needs to borrow some cash to develop it, and is willing to return 20% interest on what he borrows. Are you saying that no-one would lend this guy money and instead everyone would choose to keep earning a much lower interest?
This is time travel trading, Apple is one out of hundreds investments that really succeeded, most of the investments I know just threw money into the river and never saw any return. Comparing a possible return of a future investment or a possible super return of bitcoin's appreciation, no one will lend out bitcoins. Loan is like a stimulus injection that motivate people to work, but to know who will buy their product is just like lottery
None of those assets can be moved cross the globe in an hour. Bitcoin is to make these assets virtualized and eliminate the cost of ownership
