Take that a few steps further. Why not use 99999999999999999999999-bit
keys? Because they are much more difficult to compute. In fact if you go
above a certain key size, since IIRC the exponent e is standardized and
thus limited, your discrete logarithm is no longer discrete and so your
key security just vanishes.
In any case, 4096 bits will be secure for some time to come, and yes
8192 bits would be even more secure. We can take that as far as we wish
but there are limits in the standard, in compatibility, and in the
