The boat will be fine, as you say its designed to be kept in a bag.
The only way you may have a problem is if its stored with external weight on it (I once viewed a boat that had been stored with the engine laid on top of it that didnt look to clever
) or if left for a very extended time without use (3+ years).
Dont worry about using talc, as long as its put away dry and remains dry it will be fine.
