Well, after Dobbs, good luck with that.Any distinct group of voters has power, it's not like the liberarians are unique in that sense. What makes them unique is that they are A) ideologically distinct, and B) not very numerous, and the latter bit is the issue. Vs trying to reach to, say, normie soccer moms that aren't politically engaged and only pull the lever out of habit, where even getting a small fraction of them to flip will earn tons of votes.
The GOP got rid of RvW, rightly and justly; that does not mean it did not have an impact on the GOP's favorability among suburban women.
Edit: Also, libertarians are not a shrinking political group, they are a growing political group, and the hardcore base of the GOP is shrinking, so...
