Bankers need to play it safe. When they make a loan, they need a high degree of confidence that they will make the money back (plus some). A banker is most confident in a business plan that points to others already successfully doing what you intend to do.
But entrepreneurial success doesn’t come from repeating what already exists. Entrepreneurial success comes from breaking the rules or making new ones. Entrepreneurial success comes from being the first. But bankers want you to be the second, or the fifth, or better yet, the hundredth.
When a banker likes you, your business idea is likely already stale. Consider alternatives.
