Silly to worry about such things, especially digital technology which won't even be worth much in few years. You could just as likely get in a car accident on the way there or back (hopefully not of course) and do way more than $2k damage, but your not going to keep your car parked in the garage are you ?
Now if its such a venue that you really think theft, and/or perhaps armed robbery are likely, or the crowd is actually all over the stage and drinks are routinely poured onto gear, bottles are thrown etc, then my question would be more of why would you want to play there in the first place ?
I've been to hundreds, maybe eve thousands of shows, and I can't recall ever seeing anyone spill a beer right into an equipment rack. Few drinks can be spilled sure, but out of all the square footage in the venue, the odds of getting into your gear are pretty rare.
I'd say you have a much better chance falling off the stage, tripping over a cable etc. That is stuff I have seen happen, sometimes with some serious physical injury and medical bills, broken headstocks etc.
To me one of the main advantages about an Axe is that you can have great tones from a small and easy to carry, and replaceable, little 2 space rack.
I wouldn't bring a big collection of rare handbuilt amps, next to impossible to find effects etc on the road, leave that stuff at the studio, but the Axe can give you the next best thing, no doubt why you bought it.
Its simply an amazing live performance tool. Scenes are simply awesome when playing live
Besides, someone might break into your home while your at a gig and steal your gear......how ironic would that be!
