If the fee to make a transaction to buy a pen is too high then clearly Obyte becomes less valuable to use.
Less valuable but enough less valuable to buy pen?
So whats the reason it is not a problem? Is that reason 'market decide' or is that reason 'second layer solution' or is that reason 'it is not gonna happen than gbyte will be worth so much' ?
If 'market decide' is a reason why fixed fee is not a problem why you are talking about solutions? We don't need any solution if what you are saying is correct. What solution you want for?
Because there are more important things to work on now?
How do you know that the price of 1 BTC will be high enough in 100 years that miners could mine just for transaction fees and no rewards? You don't know, you can't know, but it's a far enough that you can predict after 20-30 years if it's ever going to happen or not. Same way here, the idea is that it would work out like that, but since we are not there yet, we can't really tell, so we need to wait and see.
Fee is not that fixed, it depends how much you post to DAG. Obyte is not just for payments, much more can be done on it.
