Noob question about opening a dedicated account for poker BR

[I.Rowboat]

Apologies for asking what is obv. a rudimentary question, but at least it should be an easy one to answer.

With the upheaval/change due to the NT withdrawal from the US market, I need to change the way I hold my BR. Currently, I have most of it (~$50k) on my primary playing site. Although I can open another eWallet account somewhere else, I like the certainty holding the funds in a B&M bank account. I would also prefer to keep my BR separate from our regular household finances. Is there any reason NOT to establish a second, separate interest-earning checking account just for poker? I already report/pay taxes on my poker income, so tax avoidance is not an issue. I realize I lose the flexibility of easily moving money to another site, but with NT's departure, that seems like a thing of the past. Besides, I'm happy at the site at which I primarily play and don't anticipate changing, unless they completely withdraw from the US market, at which point I may not be playing anywhere online, anyway.

Thanks in advance.
