This has all been explained ad nauseam. Nothing you have stated proves anything I said incorrect.
Federal prosecutors didn't think sedition would stick for most of the rioters & they didn't want them to walk free by overcharging them & they are more useful to the prosecution in building the case against Trump & the other ringleaders.
Do you really think you understand the application of federal law better than career federal prosecutors?
BTW, some of these assholes, mostly the ringleaders, did get slapped with sedition charges.
