Could increasing Block size solve the "End of mining" issue Disclaimer: I am new to this forum and Bitcoin/cryptocurrency in general.

After all 21 million bitcoins are released into circulation, it seems that the incentive to mine is gone unless transaction fees are used. But if transaction fees are too high the incentive to use Bitcoin is reduced.

If the block size is increased the total number of transactions per block would increase, which results in more total reward for that block. This would also allow individual transaction fees to be quite low.

So, is this a feasible way to solve the "End of mining" problem?
That will be part of the solution, of course. But it's already assumed that in the far future there will be more transactions. That's not a solution in and of itself.

Keep in mind also, that the more transactions there are, the more valuable the system is, and so the greater the incentive to attack, and the more mining is required to defend it.
