"... william law alleged that joseph smith had sought to
control by ecclesiastical authority the financial affairs of the saints."
The Laws only arrived in Nauvoo after assuring themselves that the chances to make money were good. After their break with Joseph Smith they could not sell their land because the majority of potential buyers were Mormons who obeyed Joseph Smith's insistence that members only buy and sell through him as trustee in trust of the church. (see below for why that was not untypical behavior)

Going back to Kirtland, to possibly Joseph Smith's most mentioned "fraud" with the Kirtland bank: "In May of 1837, a general banking panic sparked in the eastern states and spread across the country. Joseph Smith withdrew from the Safety Society in June, and publicly warned the Saints about continuing to use the Safety Society’s notes. The Safety Society failed around November." http://www.fairlds.org/wp-content/uploads/2011/12/white-KSS.pdf Joseph Smith lost heavily, despite his earlier reinvestment of personal money to endeavor to keep the Kirtland bank viable.
Joseph Smith died some $100K in debt. This was largely caused by his (typical for religious leaders of the 19th century) personal finances being inextricably linked to those of the church, which he supported through his personal financing over the years. His assets were largely "illiquid", being tied up in land, and his liquid assets were always limited, i.e. he had little cash on hand; this was the situation in Kirtland for many Mormons, thus the theoretical advantages and need for a bank. There was no intended or subsequent fraud whatsoever by Joseph Smith....
