The first thought of some is that a license to operate a ham radio is worthless when the SHTF. Do what you have to do during a crisis is the thought of some regardless of rules and regulations. There of course, is some validity to this, but the point is that you are not in the middle of a crisis yet.
To practice and get familiar with a ham radio you need to get on the airwaves, and you absolutely need to know what you are doing to be able to communicate effectively using an Amateur Radio. An operator gains experience through use. To legally transmit however, you need a call sign, which is only assigned to you by the FCC after you have passed a written test and have paid all the fees.
The test is given by teams of accredited volunteers in coordination with the FCC. The FCC does not give the test.
