I might just add that the usage of the present perfect to talk about actions happening in the present is not solely and English issue. In the French language, for example, the present perfect doesn't exist - rather they use a simple present. i.e. I have = j'ai and I have got = j'ai. I have been (eg somewhere for a length of time) = I am.
“I’ve got” vs. “I have”
