defender of truth, This thread is not useless. You are at least trying to change things by getting involved.
I have got similar responses from politicians including Barack Obama about tweaking the Tax Code to protect children from sexual abuse. Most politicians have correspondents that read correspondence to politicians and write non-committal form letters like the one that you received from the Obama Administration. Only four things motivate politicians: large donations; large, passionate groups of constituents; a personal stimulus; and an idea with little downside risk/effort and exponential upside benefit.
You could write back to the Obama Administration about what laws does the President support that would effectively protect children. In 2008 President Joe Biden sponsored S. 2756 legislation to expand background checks for individuals working with/ supervising children: https://www.govtrack.us/congress/bills/110/s2756/text . It did not receive enough sponsors to be voted on the Senate floor, nor did it mandate that all organizations providing childcare or where volunteers would work with children were required to perform background checks.
The bill to revise the Tax Code would require tax-exempt organizations to perform background checks and much more.
