Hello fer,
First of all, thx u for commenting on my blog.
To address your question. Intrinsic motivation does NOT mean no external factors. It just means the reason that drives you to do something is intrinsic to (i.e. inherent part of) the behavior itself.
For instance, using singing as an example. People can definitely be motivated intrinsically to sing. This means that they sing because they just love singing. The reason that they sing is inherent (intrinsic) to the act of singing. But this does NOT mean that there is no external factors. The singer may also get praise from the audience, s/he can make other happy by singing, etc. But these are external factors to the act of singing. But they are not "the reason" that make him/her sing. Even though many external factors exist, they are not the primary driver for the behavior (i.e. singing), which is simply the act of singing, and as a result intrinsic to singing.
So even though many intrinsically motivated behaviors may have many external factors, they are not the reason that make a person carry out that behavior. Consequently, this also means that even in the absence of these external factors, they should still perform the behavior if they are intrinsically motivated.
Alright, I hope this address your question. It's a good question, so thank you for asking.
Hope to see you again next time.
