It would seem to me
But if I were to find myself in this situation (even with no ASI), I would climb to 5000 feet towards the end of the active runway and do a lot of power off stalls to get a feel of any messages the airplane transmitted prior to stalling.
Only then would I attempt a landing.
As an aside, these days, I'd have my Dynon D2 with me and operating such that even if I had no pitot system, and even if the airspeed on the D2 shows ground speed, I could get some sort of estimate of stall speed from that. One could fly a couple of 360's at 1000 feet to get some indication as to the speed of the wind which would help my estimate of airspeed at stall.
I would do all I could to avoid this situation.There is a salutary story about a pilot who, having built an open cockpit, radial engined biplane decided to perform his own test flight despite never having flown anything like that perviously.

After the remarkably short take-off in which he had not even fully opened the throttle, overwhelmed by the noise and slipstream, he found himself at about 1000' before he'd collected his thoughts,
