That rule is there because it did happen once. Cf. Germany Schaefer.

The Schaefer steal of first is an often-repeated story, but most sources have it wrong. The year & date (& sometimes opponent changes) but Schaefer never ‘stole’ first with Davy Jones on third. In each citation, the box of the game shows that Jones followed Schaefer in the batting order. The story is mentioned in Ritter’s “Glory of Their Times” & just won’t go away.
Also, the rule wasn’t changed because of Schaefer. Not only was Schaefer out of baseball when the rule was made, but he was dead.
There are three documented occasions of a player ‘stealing’ first base. Schaefer is one of them, but the ploy was unsuccessful.
August 13, 1902, Detroit @ Philadelphia, 2nd game of double-header. A’s have Dave Fultz on third & Harry Davis on first in the 6th inning. Davis takes 2nd without a throw. He goes back to first on the next pitch. Then he & Fultz pull off double steal.
July 31, 1908, St. Louis @ New York NL. With a lead of several runs over hapless St. Louis, the Giants fool around, play subs, etc. Late in the game, Fred Tenney steals second, then goes back to first & steals second again. He later argued that he should have been credited with three steals instead of the one he is credited with.
August 4, 1911, Chicago @ Washington, 1st game of double-header. Walter Johnson & Doc White are in a scoreless tie going into the bottom of the 9th. The Senators have Clyde Milan on 3rd & Germany Schaefer on 1st with 1 out, Schaefer stole second. Doc Gessler then struck out for the 2nd out. Schaefer then ‘stole’ first base. White Sox manager Hugh Duffy came onto the field to protest Schaefer stealing first. While he was arguing, Schaefer took off for second & allowed himself to get in a rundown. Milan then broke for home, but was thrown out at home by Eddie Collins to end the inning. The Senators argued that the play shouldn’t count as the Sox had ten men on the field (counting the manager.) The call stood & the Senators won 1-0 in 11 innings.
