It is not the case that A position number system with zero as a placeholder allows an infinite set of natural numbers to be represented using only a finite set of symbols
?
Set your confidence on the premises below to see your aggregate.
Reasons For
2 perspectives
Reason for 1 of 2
?
1.
Representing a number and instantiating it are distinct: finite symbols can denote infinite numbers only if an infinite medium (time, space, or computation) is available for arbitrarily long strings.
?
How convincing is this?
Think about whether this reason is strong or weak
2.
Wittgenstein's rule-following considerations show that no finite set of symbols autonomously determines its own extension to infinitely many cases without an interpreting practice.

Think about whether this reason is strong or weak
Reason for 2 of 2
?
1.
The claim conflates potential infinity (always being able to add another digit) with actual representability, a distinction Aristotle and later Cantor took to be philosophically significant.
?
How convincing is this?
Think about whether this reason is strong or weak
2.
A number requiring n digits demands a physical token of length n, so unbounded natural numbers are not representable by finite means but only by a finite scheme applied indefinitely.
?
How convincing is this?
Think about whether this reason is strong or weak
Reasons Against

Reason against
?
1.
Zero functions as a placeholder that encodes positional magnitude
?
How convincing is this?
Think about whether this reason is strong or weak
2.
Any finite set of symbols combined with zero can represent arbitrarily large numbers by varying digit positions
?
How convincing is this?
Think about whether this reason is strong or weak
