<div dir="ltr"><div>>>> Tavo me'erah on someone who *needs* someone to be motzi him with benching,<br>because he should know it. Why should a me'erah come on someone who knows<br>how to bench but chooses to be yotzei from another bar chiyuva, male or<br>
female? <<<</div>
<div> </div>
<div>I can speculate about the why, but the fact is in Biur Halachah to Hilchos Chanukah 675 s.v. Ishah Madlekes, writes that a woman should not be Motzi a man because of Me'erah, and the reason why R' Zera relied on his wife lighting was because he himself was not home, implying that had R' Zera been at home and had his wife light he would have been in Me'erah territory, despite knowing how to make the Beracha himself.</div>
