I'd really be so much more comfortable gambling in Vegas if they raised the house rake...Makes me feel like they're less likely to rig the games.

I wish my bank would charge me more on my checking account...Makes me feel like they're not going to just shut the doors and run off with my money.

...ok?

That said, I'm fine with a commission increase to 5%.  You either trust Dooglus by investing/gambling or you don't.  I don't see any other site offering the opportunity to "be the bank". Until there is competition in that space, commission is limited only by what the market will bear and Dooglus is comfortable with.
