My MK4s have made close to a 1000 shows over 30 years.
It's all about personal perspective and parameters. I must have taped 30 shows in 15 years.
If I had infinite money in the bank, I'd probably run two Schoeps rigs (omnis and cards) in a row, but that's not the case.
And it's not a 2 to 3k question. You also have to spend money on tickets, travel, hotels, food, storage concerns for your recordings... Which multiplies the bill for each new show you attend.
I just can't afford it.
With that being said, I'm happy when a Schoeps tape of a favourite artist of mine pops up.
I'm actually happy whenever a tape doesn't sound distorted, or metallic, or muffled, or any other thing that can ruin a recording.
I also don't accumulate a shitload of recordings I'm never listening to. But I'm not being critical with people who do.
Just be happy.
