I disagree. Your BB just becomes the SB, basically, but you retain position on one player. I would be totally fine with UTG straddling my blinds. I may even encourage it.
I am looking for online win-rates by position for the blinds. Basically if the win-rate for BB is less than double that of the SB, I would think having an UTG straddle would be +EV for you. One source said -40BB/100 for BB and -20BB/100 for SB are pretty standard, so an UTG straddle would be roughly neutral. I'd also argue that shortening effective stacks and retaining position on the SB are a net positive for the BB player compared to being the SB in an unstraddled pot.
Of course, the further IP the straddler, the worse it is for the blinds, as they lose their only advantage of pre-flop position, but I very highly doubt that BU straddles on your blinds makes the game unbeatable, even if those are the only times the game has a straddle. In live games I believe you are making more than enough from other positions to win even if you have to fold your blinds 100% of the time, which is not the case. Still, it would likely be highly beneficial to move to the straddler's direct right, ignoring other factors in play.
I am also highly skeptical that BU straddling is good to do, unless perhaps if you have an enormous skill edge on the table and/or stacks are deep enough that you need to double the stakes to bring them into play.
