Personally, if I made a loop and someone wanted to stick it in their live set I'd be honoured. I guess it just depends on your mindset. I'm very much in favour of "sharing the wealth". The whole dance music community thrives on people performing with other people's output - so I kind of see this as the logical destination.
I can see where you're coming from if this was just concerning the samples you use to make your track parts, but not the track parts themself.

However nothing wrong with sharing the sample love. What you do with them at that point is up to you though.
