If small businesses in the EU can't globalize, how come they were selling to the UK in the first place? Could it be the SM helped them?
If small businesses can't compete with the big corporations plus get clobbered by EU dogma, how come so many of them are still alive, innovating and prospering?
You may be interested to learn that SMEs in the EU employ a significantly higher proportion of total company employees (66.3%) than in the UK (53.5%), that these companies generate a higher proportion of total corporate sales (55.8%) than those in the UK (47%), which suggests the business environment in the EU27 is more favourable for SMEs than you suggest.

The UK figures are actually the lowest of the lot. Malta has the highest.
It is quite possible that some small (and maybe even some not so small) companies on each side of the Channel will ultimately decide that the business on the other side is no longer worth it due to higher transaction costs. That would be a shame of course, and something that could have been avoided had the UK not insisted for largely ideological reasons on leaving the benefits of the customs union behind. Brexit has always been a lose/lose proposition.
