But the original post said that aircraft taxi because their wheels reduce
friction. No mention of energy or force. So if the statement is true,
movement results from a lack of friction alone, so zero friction should
produce infinite speed (or lightspeed if one allows the speed of light as an
absolute upper limit).

However, space (especially near space) is not frictionless.

So, would having wheels reduce the friction in near space?
