b4nnyGo watch WarOwl or Greekgod or any new TF2 player playing competitive mode for the first time. They didn't care nor notice any issues with the enforced graphics settings. Your perspective is biased because you are too attached to your FPS configs. Level playing field, standardization and accessibility is a necessity for the integrity of the competitive mode long term. That said, they should definitely add as many commands/settings as possible to the options menus so that FPS config level graphics can still be achieved while maintaining fairness.
well the game runs like shit for a lot of people without fps configs. maybe their perspective is biased because they dont want to play with 60 fps on a 10 year old game.
if valve were to add the level of customization that is available with fps configs to the advanced options in-game there obviously wouldn't be any argument to be had, but i would very much doubt they would do that because it would involve a lot of work.
even then i don't really understand the level playing field argument. anyone who is able to play well on default graphics probably will, and anyone who isn't would use an fps config. unless valve think it would be unfair on the hightower heavy mains trying out comp for the first time who don't know how to use an fps config, in which case they're going to get steamrolled anyway.
