I understand what you're trying to say and I agree with it to an extent. There are some other points worth considering, however.
For one thing, you overstate the effect that an influx of new talent has on a generational player. I have serious doubts that an influx of black pitchers would have any more effect on Ruth than it did for a guy like Stan Musial during the height of integration ( https://www.baseball-reference.com/players/m/musiast01.shtml ). Even against the elite pitching of the playoffs, he was even better than he was in the regular season. These guys are just on a different level and will excel against any pitchers.
Consider the other elite players of the era like Tris Speaker, Rogers Hornsby, and Harry Heilmann. Even if you expand the pool of players to include the negro leagues, it's fair to say that they were all top 10 players of that era. Ruth absolutely dwarfed their statistics. Consider the top white players of today like Donaldson, Harper, Judge, etc. and the difference is not nearly as large.
Babe Ruth was so good that he changed the way that the game was played. He was putting up 50+ HR seasons when the next best player wasn't even reaching 20 and entire teams didn't hit 50. He was putting up 15 WAR seasons when the next best players were barely reaching half of that value. Trout isn't doing that. While his accomplishments are remarkable, there are always other guys like Jose Ramirez with similar reaults in any given year. He's not doing anything that has never been done before like Bonds or Ruth.
Also, let's not forget the pitching aspect. Babe Ruth was one of the top pitchers in the league for a short time and anecdotal evidence suggests that he could have had a Hall of Fame career on the mound as well. How do we quantify this? I'm not sure, but I can just imagine that with modern training like Ohtani has, he could have been a 2 way sensation for the majority of his career. The level of talent it takes to be an all-time great on both sides of the ball is just incredible.
