Apart from the post points you have mentioned for me bitcoin gives an immense stability to me by providing Internet based income. This income is additional for me with which I can buy many stuff for me and my family. I'm grateful to it in many ways, as it has given the financial freedom which I couldn't get from real job that I'm doing. Moreover time is the barrier in real life.
Exactly, it not only gives online income for those freelancers who work for international clients but also it helps them to accept, hold and spend funds. I live in a country where Paypal has serious restrictions and thus one has to pay excess cost in order to spend the funds as we are not allowed to hold any amount in our Paypal wallet. Bitcoin is great not only in terms of flexibility but also in the case of cost of the transaction.
