By those standards, nothing can be measured. Everything is measurable only with a degree of uncertainty.
Some things have more uncertainty than others (compared to what the number would be used for) but we have created techniques to deal with that in practise too (hedging, optionality.)
Maybe you have a personal threshold for a level of uncertainty below which things count as measurable and above which they don't, but you're imbuing the word "measure" with subjective characteristics at that part -- not to be confused with its objective meaning.
