Your logic is backwards: a higher universal speed limit would make it
HARDER for space travel -- in fact: impossible.

The extreme cases (infinty for Newtonian physics, c for relativity)
clearly show this as follows. At a steady 1-G acceleration, it would
take tens of thousands of years to get around the galaxy in the former
case. In the latter case, with a finite speed limit of c, at a steady
1-G acceleration, it would take about 20 years or so go get virtually
ANYWHERE.

At an even more extreme: if c were almost 0, you could get anywhere in
almost no time at all!
