You have any proof for your claim that there has been a 90% reduction in gun dealers in the past 15 years?
They changed the dealer license rules. They now require a fixed place of business, a store that conforms to local zoning rules. All those who had formerly sold from home, or other place of business as a secondary op, where not renewed.
Below. A large number of these licenses were individuals selling an occasional gun from home or at shows, not commercial enterprises.
IF this guy was omitting background checks for "special" cases, and not reporting multiple handgun sales, I'm glad there's one less. These are the abuses that lead to more regulation.

America Once Had More Gun Dealers Than Gas Stations, Now Only Five States Do: Alaska, Idaho, Montana, Oregon, and Wyoming
WASHINGTON, DC—The number of gun dealers in America has dropped by 190,726 since 1994 according to a new study released today by the Violence Policy Center (VPC). The study (see http://www.vpc.org/studies/dealers.pdf) found that the number of Type 1 Federal Firearms Licenses (FFLs) plummeted 78 percent: from 245,628 in 1994 to 54,902 in 2005. (The Type 1 FFL is the basic federal license required to sell guns in America.)
The 1992 VPC publication More Gun Dealers Than Gas Stations first focused national attention on abuses by FFL holders and revealed that at the time of its release the number of Americans who possessed the Type 1 FFL outnumbered gas stations 245,000 to 210,000. The bulk of the licenses were held by illegitimate "kitchen-table" dealers who operated out of their homes or offices, an unknown percentage of which were actively involved in criminal gun trafficking. As the result of policy recommendations contained in the study that were implemented under the Clinton Administration, today only five states have more gun dealers than gas stations (see chart below). The full study contains information for all 50 states as well as policy recommendations.
| State | Number of Gun Dealers | Number of Gas Stations | State | Number of Gun Dealers | Number of Gas Stations |
| Alaska | 844 | 229 | Oregon | 1,479 | 1,146 |
| Idaho | 682 | 663 | Wyoming | 550 | 401 |
| Montana | 1,017 | 597 | U.S. Total | 54,902 | 121,363 |
California posted the largest decrease in the number of gun dealers of any state in the nation, dropping from 20,148 in 1994 to 2,438 in 2005—a drop of 88 percent.
VPC Policy Analyst Marty Langley states, "The sharp drop in gun dealers is one of the most important—and little noticed—victories in the effort to reduce firearms violence in America. The dramatic drop in dealers aids not only federal law enforcement, but cities and states as they continue their efforts to reduce illegal firearms trafficking and firearms violence."
